Question

What must `n` be if the ratio 6:7 is equivalent to 36:`n`?

Answer 1

`n` = 42

Explanation:

You first do `\frac {36} {6}` which equals 6. This is the constant that you are going to multiply by 7. Since you have to multiply by both sides on a ratio, you do 6`xx`6 and 6`xx`7. This equals 42.
The final ratios are:
6:7 and 36:42
