In Mr. Carter's math class we are learning about fractions. We are multiplying, adding, and subtracting. Here is the problem. 3/5 + 4/9=?
Here is how to add fractions.
Step 1: Cross multiply
How to cross multiply: Take the bottom number of one fraction and multiply it by the numerator (top number) of the other fraction. Do this for both fractions. Replace the top numbers with the results you get for each one. 27/5 + 20/9=
Step 2: Add the top numbers.
Step 3: Multiply the denominators. 47/45
Step 4: Now reduce fraction. 1 and 2/45
