ADDING and SUBTRACTING FRACTIONS

Today in math class, after we went over our homework we learned how to add and subtract fractions. Adding and subtracting fractions is like adding and subtracting numbers except there is a numerator and a denominator. Both the numerator and the denominator are added and subtracted by each other so like the line thing that separates them is like a line separating two different kinds of problems. This is easy until there are letters that I forget what they are called come into play. When you add or subtract a fraction with a letter/symbol thing, you have to times the numerator by what ever the denominator was multiplied by. So three over five and W over 15. Because the two denominaters are 5 and 15, you divide and you get 3 so you do 3 times 3 and get for the other denominator 3W. This is adding and subtracting fractions
