What is ratio of 15 and 75 in lowest terms?

Answer 1

15:75::1:5

Answer 2

The ratio of 15 to 75 can be simplified by dividing both numbers by their greatest common factor, which is 15. When we divide 15 by 15, we get 1, and when we divide 75 by 15, we get 5. Therefore, the ratio of 15 to 75 in lowest terms is 1:5.

Answer 3

This is all about factorising.

Firstly yo have to find the biggest number that will go into both 15 and 75.

15 goes into both 15 and 75.

Divide both numbers by 15, (15/15=1) (75/15=5)

Therefore the ratio in its lowest terms is 1:5

If you can not recognise that 15 is the highest common factor straight off then look for smaller ones each time.

e.g.

divide by 5. Ratio = 3:15

divide new ration by 3. Ratio = 1:5
