Question

How can you simplify 18/30?

Answer 1

Simplified it would be 3/5

Explanation:

Start by dividing them by any common factor that they both have. Both are divisible by 3, so we divide both numbers by 3.

18/3 = 6

30/3 = 10

6/10

At this point, both numbers are still divisible by 2, so we divide them again.

6/2 = 3

10/2 = 5

3/5

Since these numbers share no factors, we know we are done.

Answer 2

3/5

Explanation:

Think: What's the greatest common factor of 18 and 30? It's 6.

Starting with 18/30, divide both numerator and denominator by 6, obtaining:

3/5
