Question

12:21 and 32:56 are in proporion ​

Answer 1

Step-by-step explanation:

no they are not in proportoon

Answer 2

Answer:

12:21 and 32:56 are in proportion because in a proportion the products of extremes = products of mean.

In this case the means are 21 and 32

and extremes are 12 and 56

There fore;

21 x 32 should be equal to 12 x 56    (if it's true then these ratios are in proportion.)

21 x 32 = 12 x 56

672 = 672

Hence these ratios are in proportion.
