Question

Do the ratios 7 4 and 42 24 form a proportion?

Answer 1

Yes because 42 divided by 7 is 6 and 24 divided by 4 is 6 which makes the ratio 7:4 and 42:24 equal to each other

Answer 2

yes

Explanation:

a ratio is a special form of a fraction, but it is a fraction.

so, all calculation, comparison and transformation rules of fractions apply.

7:4 = 7/4

42:24 = 42/24

and because

7/4 × 6/6 = 42/24

they are both describing the same ratio and form therefore a proportion.

a proportion simply means that two fractions are equal.
