Q: In our first example, using 9/11 and 2/4, we decided to use 44 as the common denominator. But remember, we can't just change the denominator without multiplying the numerator by the same amount as well. Here's how we turn it into an equivalent fraction: We know 11 x 4 = 44 (this is how we found the number 44 to begin with, but you can solve 44 11 if you forgot). Multiply both sides of the fraction by the same number to get the result: (9 x 4 ) / (11 x 4) = 36/44 Here's the second fraction in our example, 2 / 4, transformed into an equivalent fraction using 44 as the denominator: 4 x 11 = 44 (2 x 11) / (4 x 11) = 22/44. Once both fractions use the same denominator, you can add or subtract the numerators to get the answer: Addition: 36 / 44 + 22 / 44 = (36 + 22) / 44 = 58/44 Or subtraction: 36 / 44 - 22/44 = (36 - 22) / 44 = 14 / 44 If the numerator ends up larger than the denominator, you have a fraction larger than 1 (an "improper fraction). You can make these into a mixed number, which is easier to read, by dividing the numerator by the denominator, and keeping the remainder as a fraction. For example, using the fraction 58 / 44, we get 58 44 = 1, with remainder 14 left over. This means our final mixed number is 1 and 14/44. If you're not sure how to divide the numbers, you can keep subtracting the bottom number from the top, writing down how many times you've subtracted. For example, convert 317 / 100 like this: 317 - 100 = 217 (subtracted 1 time). 217 - 100 = 117 (subtracted 2 times). 117 - 100 = 17 (3 times). We can't subtract any more, so the answer is 3 and 17/100. Simplifying a fraction means writing it in its smallest equivalent form, to make it easier to use. Do this by dividing the numerator and denominator by the same number. If you can find a way to simplify the answer even further, keep doing it until you can't find another. For example, to simplify 14/44: The numbers 14 and 44 are both divisible by 2, so let's use that. (14 2 ) / (44 2) = 7 / 22 There are no numbers that divide evenly into both 7 and 22, so this is our final, simplified answer.
A: Change the first fraction to use the common denominator. Do the same for the second fraction. Add or subtract the numerators of the fractions to get the answer. Convert improper fractions into a mixed number. Simplify the fraction.

Q: For this method, you'll want one with a wider mouth. As with the paper mask version, it should be about 5 liters. Visit your local Halloween or costume shop. Get a rubber zombie maskthe more realistic, the better. Politician masks are good to use, too, but they can be more frightening than zombies: use with caution. Backfill the mask with a balloon by putting it mostly into the jar, behind the mask, then inflating it until the mask is pressed up against the glass. Drop in a couple fake eyes, and some human hair, and fill the whole thing with water. You can add a drop or two of yellow and green food coloring to get that lovely formaldehyde hue. Add a little garden-variety dirt and shredded brown recycled paper towel to simulate decomposition.
A: Find a suitable jar. Find a suitable mask. Stuff the mask into the jar. Add accessories. Display where it's most likely to gross people out.

Q: You can purchase felting wool online or at a craft supply store. Buy a few colors that complement each other to create your brooch. Felted wool is not regular wool. It will come in soft, puffy bunches.
A: Purchase felting wool in a variety of colors.

Q: Almost any teacher will go to extra help. Don't be too proud to ask you'll develop a relationship with your teacher and it will help a lot. Your teacher will appreciate that you came in looking for more help and the teacher will know what you need to work on in the future. This is highly recommended. You have to be honest with yourself here. Is the issue that you aren't trying hard enough, or that you really just don't understand math? If you're not trying hard enough, you need to work harder to practice on your own. There's no way to understand math if you aren't willing to put in the work. However, if you have been practicing on your own and you just can't wrap your head around a certain subject, then it's perfectly logical to ask for help. If you're willing to spend money, hiring a professional tutor can be a huge help when it comes to understanding a subject. Professional tutors are often very expensive, but if you hire an older student the price might come down. Tutors will sit down with you one on one and work you through your problems. If you don't want to hire a tutor or go to extra help another good option is to ask a peer. There is bound to be someone in the math class who understands the concepts well. Find this person and develop a relationship with them. Ask them if they would be willing to sit down with you over lunch and help you with a couple of topics you are struggling with. Don't take advantage of them and never try to copy their answers just use them as a resource. There's no reason to be too proud to ask for help. That's a good skill to develop in life.
A:
Go for extra help. Practice more on your own. Hire a tutor. Look to a friend or peer for guidance.
