Proportions- determine if each pair of ratios forms a proportion. show all work! 30 12 and 80 32

Answer

Yes they form a proportion.

Explanation

Ratio is a division. For the two ratios to be proportional, then they must be the same after been simplified to their simplest form.

So in this case we have to ask ourselves whether 30/12 = 80/32.

30/12 = 2.5

30/12 = 15/6 = 5/2

80/32 = 2.5

80/32 = 40/16 = 20/8 = 10/4 = 5/2

The two ratios are the same, so we can say that the ratios are proportional.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
