What is to reduce?

Answer 1

To reduce, all you have to do is to simplify the fraction.

Example, Let's say you have 5/10ths, as you can see, 5 is half of 10, so, the number reduced would be one half or 1/2. It goes with other numbers too like, 7/14 or 8/24.

Another way to simplify a fraction that is not exacly one half but can still be reduced,

like 7/21. 7 is not 1/2 of 21, but, it is 1/3 of 21. You see, 7 goes into 21 three times,

so therefore, it is 1/3.
