To find out the **simplest** form of any fraction, you need to discover the lowest common denominator of both numbers.

This is found by dividing both numbers that make up the fraction (in this case **56** and **64**) by the lowest number by which both numbers are divisible. It sounds tricky, but it's really quite easy.

**56**and

**64**are even numbers, it's obvious they can each be divided by 2:

56 divide 2 = 28

64 divide 2 = 32

So, you could say that 56/64 is the same as 28/32, and you'd be right, but the fraction can be simplified further. 28 and 32 are also divisible by 2:

28 divide 2 = 14

32 divide 2 = 16

So, we'd then have 14/16 (fourteen sixteenths). But again both numbers are divisible by 2:

14 divide 2 = 7

16 divide 2 = 8

This gives us the fraction 7/8 (seven eighths). 7 and 8 do not share 2, or any other number aside from 1, as a common denominator. Therefore, the fraction 7/8 cannot be simplified further, and the answer to your question is **56/64** written in its **simplest** form is **7/8**.
