How do you reduce 100 over 360?

Answer 1

To reduce a fraction, you need to find common factors for the two numbers. Think of numbers that you can divide into both 100 and 360.

Both numbers are a multiple of 10 because they end in zero. To start, let's divide both numbers by ten to get 10 over 36.

Let's keep going: both numbers have two as a factor because they're both even. When we divide both 10 and 36 by two, we get 5 over 18.

Since 5 is a Prime number (you can't divide it by anything but 1 and itself), you can't reduce the fraction anymore. Your final answer is 5 over 18.
