solving gives x = 14

Which benchmark is between 3/7 and 16/20 <br><br> Answers between 1/2 and 1 whole?
kicyunya [14]

Answer:

140

Step-by-step explanation:

I think you mean "lowest common denominator" where you use the word "benchmark."

The LCD of 3/7 and 16/20 is 140; 140 is the smallest number evenly divisible by both 7 and 20.

Then 3/7 → 60/140 and 16/20 → 112/140.   112/140 is between 1/2 and 1.
