Question

what is the equivalent ratio to 1:4 and 8:

Answer 1

you can solve this looking for a number than multiply 1 and the product is 8, so

$1\times8=8$

so, the number is 8

yo have to multiply 4 for the same number to preserve equivalence

$4\times8=32$

so, the equivalent ratio is

$\frac{1}{4}=\frac{8}{32}$
