Fractions don't always have the same denominators, and in order to add or subtract those fractions, you must first find a common denominator. To start, locate the denominators in the fractions you're dealing with. For instance, in the equation 5/8 + 6/9, the denominators are 8 and 9. To find a common denominator, you need to find the least common multiple of the two numbers, which is the smallest positive number that's a multiple of both original numbers. To find the least common multiple of 8 and 9, you must first go through the multiples of each number: The multiples of 8 are: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, etc. The multiples of 9 are: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108, etc. The least common multiple of 8 and 9 is 72. Multiply each denominator by the correct number to achieve the common denominator. Remember that whatever you do to each denominator, you must also do to its numerator. For the fraction 5/8: to achieve the common denominator of 72, you multiply 8 x 9. Therefore, you must also multiply the numerator by 9, giving you 5 x 9 = 45 For the fraction 6/9: to achieve the common denominator of 72, you multiply 9 x 8. Therefore, you must also multiply the numerator by 8, giving you 6 x 8 = 48 The new fraction will have the common denominator and the product of the numerators multiplied by the same values: The fraction 5/8 becomes 45/72, and the fraction 6/9 becomes 48/72. Since they now have a common denominator, you can add the fractions 45/72 + 48/72 = 93/72. Don't forget to reduce, solve, or convert improper fractions to mixed numbers when applicable and necessary.

Q: Though it may be tempting to always apply foundation before any other makeup, doing your eye makeup first will prevent any smudging or running of your foundation. Get in the habit of doing your eye makeup first, followed by your foundation. If you have oily eyelids, you may want to apply eye primer to your eyelids with a clean makeup brush. The primer will help the eyeshadow stick to your eyelids smoothly and help the shadow stay on your eyelids. You may also want to apply a thick layer of loose powder under your eyes. This will make it easy to dust off any eyeshadow that falls on your undereye area. Lay out the three eyeshadows in front of you and position yourself in front of a mirror with good lighting. Keep tissue and Q-tips nearby as well to clean up any eyeshadow that gets on your eyelashes or face. You will need two clean eyeshadow brushes to create the gradient smokey eye look. You will use one eyeshadow brush to apply the three eyeshadows. You will then use the other eyeshadow brush to blend the colors once they have been applied. Look for brushes that are have small, rounded bristles to use for the eyeshadow. A blending brush is also a good option, which will often be small and have fluffy rounded bristles to make blending easier.
A: Start with a bare face. Get two eyeshadow brushes.

Article: Send a text to your partner, friend, or family member, casually describing a major task you need them to do. For example: "Hi, some internet friends from (distant country) are in town, but I decided to relax today. I told them you could show them around instead, maybe drive them to (nearby city)? They'll be at your house soon." (To a friend about to return from vacation) "Welcome home! Thanks for letting me stay in your house. I'm borrowing your clothes for a few more days, but I'll return the stained ones by the end of the week." Have a text conversation, but ignore all the replies from the other person. Instead, send this sequence of messages, waiting for at least thirty seconds between each one. Hey, where are you? Yeah, almost ready. I don't think he knows anything. It's happening in a few minutes. You definitely said grapefruit juice. Susan's bringing the ramp. Wait, is this going to (other person's name) too? Cancel everything, we'll move it to next week. Ask silly questions, or riddles with trick answers: "If a cat always lands on its feet, and toast always lands butter-side-down, what happens when you tie toast to a cat's back?" "If a plane crashes in Antarctica, in what country are the survivors buried?" (Answer: Why do you want to bury a survivor?) Visit an upside-down text flipper, and type in your message. This will convert your message into upside-down text. Not all chat programs, email applications, and browsers can display these characters, so the person you send it too might only see a row of squares or question marks.

Article: Use a measuring tape to measure all 4 sides of your table, then add them together. This will tell you how much elastic you will need to buy. You will need to buy enough elastic for all 4 sides of your table, even if it will be up against a wall. If your table is circular, wrap the measuring tape around the perimeter. Wrap 58in (1.6cm) wide elastic around the edge of your table. Tie the ends together in the back of the table with a double-knot, or overlap them and secure them with a pin. Pin the elastic to the tablecloth every 6 to 12 inches (15 to 30cm) so that it doesn't slide off. Match the elastic color to the tulle. Fold-over elastic is a great option because it comes in many colors. Wrap the elastic tightly enough so that it doesn't slide off, but loose enough so that you can still slide your finger under it. They are about 6 inches (15cm) wide, and you can find them near the ribbon or wedding section of a craft or fabric store. If you can't find any, buy regular tulle off the bolt at a fabric store, then cut it into 6in (15cm) wide strips. Plan on getting 2 to 3 spools that are 100 yards (91m) each. You can use all 1 color, or you can use multiple colors for a more interesting effect. For example, you can use light pink and dark pink instead of just light pink. Try a rainbow of colors: pink, orange, pastel yellow, mint green, pale blue, and light purple. For a more magical display, consider using sparkly or glittery tulle. Measure the height of your table first, from the floor all the way to the table top. Double your measurement, then cut your tulle into strips that match that length. How many strips you cut depends on how much coverage you want on your table. Cut just a few for right now. Cut a piece of cardboard to the height of your table. Wrap the tulle around it, then cut the bottom edge to separate the strands. Take 1 strip and fold it in half so that the narrow ends match up. Slide the folded end behind the elastic to make a loop, then pull the 2 tulle tails through the loop to tighten the knot. Make sure that the folded end is pointing down when you slide it behind the elastic, not up. The tighter you make the knot, the fuller your tutu will be. Make sure that the knots are touching each other. If you leave too much space between the knots, your table tutu won't be very full. If you run out of strips, cut some more. If the table will be against a wall, you only need to cover the sides that will be visible. If a pin gets in the way, you may need to move it.
Question: What is a summary of what this article is about?
Measure the circumference of your table. Wrap elastic around the table and secure it in the back. Purchase some spools of tulle. Cut your tulle into strips that are twice the height of your table. Secure the first strip to the elastic with a slip-knot. Continue to tie the tulle strips around the table until the elastic is full.
