True or False? Tell whether the pair of ratios form a proportion. 49/21 and 28/12 Please explain why you chose what you chose​. Need answered asap:-)

Answer 1

True, they form a proportion because their cross-multiplication products are equal.

Explanation:

`(49)/(21) =(28)/(12)` True or False?

If they are a proportion, the products you get from cross-multiplying are the same.

Multiply the left numerator by right denominator:

49 X 12 = 588

Multiply the left denominator by right numerator:

21 X 28 = 588

588 = 588

Therefore it is true, 49/21 and 28/12 form a proportion.
