ratios equivalent to 12:14

Question

I am doing a problem on ratios and I do not know how to find equivilent ratios. Can you help?

Answer 1

When you see a ratio, look for common factors of the two numbers that make up the ratio. In this case 2 goes into both numbers: 12:14 is the same as 6:7.

Now we can reverse the process. This time we multiply the reduced ratio by other factors. For example, 3:

18:21 is also the same as 6:7.

You can make other ratios by multiplying the numbers by another common multiplier like 5:

30:35.

And so on.
