Question

Are these fractions proportional? 1/3 = 6/20

Answer 1

Answer,

No

Explanation,

To find out if a pair of fractions are proportional you can use cross multiplication. Only fractions that are equivalent to eachother are proportional.

1/3 = 6/20

1 * 20 = 20

3 * 6 = 18

As we can see they are not equivalent, therefore it is not proportional.

Hope This Helps :-)

Answer 2

They are not proportional.

Explanation:

To check if the fractions are proportional, we can use cross products.

1 6

----- = --------------

3 20

1 * 20 = 3 * 6

20 = 18

This is not true, so they are not proportional.
