Question

What is 18/30 in simplest form?

Answer 1

3/5 is the answer because I cross multiplied 30 x 3 is 90 and 18 x 5 is 90

Answer 2

To simply this, you just divide the numerator and denominator by its GCF (Greatest common factor)

Factors of 18 : 1,2,3,6,9,18
Factors of 30 : 1,2,3,5,6,10,15,30
As you can see, the great common factors of 18 and 30 is 6.

So divide 18 by 6 and 30 by 6, and you get 3 and 5

Therefore, the simplest form is 3/5
