Determine which statement is a true proportion. question 7 options: 10/9=11/10 1/2=3/4 12/42=10/35 48/56=40/48

True proportion: 12/42 = 10/35.

Step-by-step explanation:

You can do this by performing the division. For example 10/9 = 1.11111.. and 11/10 = 1.1 so they are not proportional.

Or you can factor numerators and denominators and look for common factors.

For example 12/42 = 2 * 6 / 7 * 6 = 2/7

and 10 / 35 =  5*2  /  5*7  = 2/7.

So these 2 are proportional.

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
