In one sentence, describe what the following article is about: You will have three numbers to use in your calculation. For example, say that Joe Smith plays for 6 innings in a 9-inning game and allows 3 men to score. For this, divide the number of earned runs by the number of innings played. Following our example, it would be 3/6, giving us the number .5. That means we would take our number of .5 and multiply it with 9, giving us 4.5. Depending on your preference, you can calculate ERA two ways. The first (shown above) is ERA= total innings(earned runs / innings pitched). You can also formulate it as ERA = earned runs x total number of innings / innings pitched. Test your answer using the alternate method.
Summary: Gather your information. Make the first calculation. Multiply this number with the total number of innings. Test your number.

The tongue's unique texture and large surface area makes it host to millions of bacteria, which can travel to the teeth and gums and cause cavities and gingivitis. The teeth gather plenty of bacteria themselves, but unlike the teeth, the tongue is not a smooth surface. It follows that even more bacteria accumulate in the taste-buds and small pits on the tongue. Just rinsing the mouth with water is insufficient to remove the bacteria on the tongue, primarily because the bacteria gather in what is called a "biofilm"-- a sticky, gooey, living layer of bacteria. It must be disrupted by rubbing or scraping to fully remove it. The bacteria that live on the tongue cause a chemical reaction that produces volatile sulfur compounds, which results in bad breath. Tongue brushing can also remove traces of odorous foods like garlic and onions, which can also improve your breath. Many people with bad breath are not aware that they have it. Its a good idea to practice good oral hygiene, including regularly cleaning the tongue, in order to reduce the chance that you are one of them. Certain foods and health conditions can cause a colored or filmy appearance on the surface of the tongue. Brushing the tongue can eliminate this problem. Foods containing dyes like cupcakes, lollipops, or popsicles can temporarily dye the surface of the tongue. Brushing the tongue can reduce the coloration of the tongue, making it less noticeable to others. Some illnesses like oral thrush or syphilis can cause a buildup of bacteria or fungi on the tongue that cause a filmy, white appearance. In some cases, the white film cannot be brushed off. Be sure that you see your doctor if you suspect that your filmy tongue is caused by an illness. Certain medications like antibiotics or Pepto-Bismol as well as certain illnesses can also cause a startling discoloration of the tongue called "black hairy tongue," which is caused by an overgrowth of yeast in the mouth. The condition is not serious and the discoloration can be brushed off with a toothbrush or washcloth, although it might be a good idea to see your doctor to determine the cause.

Q: Before attaching the flowers to the crown, you will need to cut small sprigs of baby's breath. Try cutting the stems so that they are similar in length. You want to leave a few inches of stem. This will make it easier to attach the stems to the crown. If you want, you can tape together a few sprigs of baby's breath to create a small bunch and then attach the bunch to the base of the crown. This will make a fuller looking crown. Take one sprig or bunch and tape it to the crown using floral tape. Lay the flowers horizontally along the crown base. Make sure to tape the entire stem so that you do not have any stems sticking out from the crown. Before attaching the flowers, attach the two ends of wire so that it is in the shape of a crown. Once the flowers are on, it is harder to bend the wire into a circular shape. Continue to tape sprigs or bunches of baby's breath all the way around the crown until you reach the starting point. Make sure the flowers are all facing in the same direction and are placed horizontally along the crown. You can place them close together for a fuller look. Alternatively, you may want to space them farther apart for a more natural and bohemian look.
A: Cut the baby's breath stems. Tape the flowers to the wire crown. Continue evenly around the crown.

Problem: Article: Ideally, the color should match your teeth, but whitening toothpaste or other methods can blend most teeth in with a bright white, plastic straw. This method is quick and easy, and the fangs are easily removed and reattached. If your straw is a bendy straw, cut off the top portion, right above the accordion bend. Otherwise, cut off about 2 inches (5 centimeters) with a pair of scissors. Or, stick the end of the straw over your tooth and look in a mirror to measure twice as long a piece as you need. Fold the cut-off piece of straw in half. Use the pair of scissors to trim to the two sides into fang shapes. Leave them attached while you trim them, so you can compare the shapes and keep them symmetrical. Don't cut too close to the fold. That area of the straw will go over your tooth, and needs to be kept intact or the fang could fall apart. Cut the piece of straw in half along the fold, separating it into two fangs. Slip these onto your canines, or onto the incisors directly to either side of your large front teeth.
Summary:
Find a white plastic straw. Cut off a small portion. Fold the piece and trim it into fangs. Cut the fangs in half and wear them.
