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.
