Question

If a picture with a length of 5 inches is made larger using a ratio of similarity of 1:3, what is the new length of the picture?

Answer 1

i dont get ratios help please?

Answer 2

A ratio is a fraction.

1:3 is the same as 1/3

Your current picture is 1/3 the size that you want.

That means all the dimensions are 1/3 the size that you want.

If "5" is 1/3 the size that you want, then what is the size that you want?

5*1/3?

That would make it smaller.

You want to go in the other direction.
