Rations to their simplest form

Question

3:12;15

Answer 1

To find the simplest form of a ratio, we need to divide both numbers by their greatest common factor (GCF).

For the ratio 3:12:
The GCF of 3 and 12 is 3, so dividing both numbers by 3 gives us:
3 ÷ 3 = 1
12 ÷ 3 = 4

So the simplest form of the ratio 3:12 is 1:4.

For the ratio 15:
In order to write a ratio in simplest form, we need to include a second number. A ratio is a comparison of two quantities. If 15 is the only number given, we cannot simplify it further unless we have a second number to compare it to.
