What is the ratio in simplest form?
12 to 28

12:28 = 3:7

Step-by-step explanation:

Try to reduce the ratio further with the greatest common factor (GCF).

The GCF of 12 and 28 is 4

Divide both terms by the GCF, 4:

12 ÷ 4 = 3

28 ÷ 4 = 7

The ratio 12 : 28 can be reduced to lowest terms by dividing both terms by the GCF = 4 :

12 : 28 = 3 : 7

Therefore:

12 : 28 = 3 : 7
