Question

Find the unknown number in the proportion 6/7 = x/106 Round your answer to the nearest hundredth.

Answer 1

Weare asked to solve for "x" in the following proportion:

6 / 7 = x / 106

so, in order to isolate x completely on one side, we multiply both sides by 106, that way cancelling the denominator that accompanies x:

106 * 6 / 7 = x

Then, x = 636 / 7

now performing the division:

x = 90.8571...

and we round this to the hundredth as requested:

x = 90.86
