Problem: how do you do fractions?
i need help with fractions and dont understand how oter things eqal 1/2 or how to multipy them.
First, look at the fraction 1/2. The denominator (on the bottom) is
twice as large as the numerator (on the top). Any fraction that has
that same ratio is equal to 1/2. For example, 33/66 = 1/2. 5/10 = 1/2.
47/94 = 1/2.
When multiplying fractions, multiply the numerators to obtain a new
numerator, then multiply the denominators to obtain a new denominator.
Example: (4/7) * (5/13) = (4 * 5)/(7 * 13) = 20/91
The process is the same if you are multiplying three, four or more
fractions. (2/8) * (1/3) * (9/16) = (2 * 1 * 9) / (8 * 3 * 16) = 18/384
