Question

Prove that 3:8 is eqivalent tp 12:32

Answer 1

3:8 can also be written as 3/8

12:32 can also be written as 12/32

$\frac{12}{32} = \frac{3\times 4}{8\times 4} = \frac{3}{8}$

So thus 3:8 is equivalent to 12:32

Answer 2

If you multiply 3 x 4 you'll get 12 and if you multiply 8 x 4 you get 32
