Question

What must you do if you multiply one number in a ratio by n?

Answer 1

multiply the others by n

If you want to keep the same ratio, you must multiply all of the numbers by n.

A ratio of 1 : 1 will remain 1 : 1 if all the numbers are multiplied by n:

1 : 1 = n : n

Comment on alternate interpretation of the question

There are occasions for multiplying the ratio by n:

x/n = 1/2

To solve this for x, we multiply the ratio (1/2) by n. This multiplies the numerator, but does not change the denominator.

x = n(1/2) = n/2
