Solve the following proportion for x.
x8 = 717
Round your answer to the nearest tenth.

90

Step-by-step explanation:

x8=717

This can also be written as

8x=717

Divide both sides by 8

8x/8=717/8

x=717/8

x=89.625

We are to round up to the nearest ten. In rounding of numbers, numbers 1 to 4 are rounded up to 0 while numbers 5 to 9 are rounded up to 1.

Numbers can be rounded up to nearest ten, nearest hundred, nearest thousand. Numbers can also be rounded up to 1 decimal place, two decimal place, three decimal place, etc.

Rounding off 89.625 to the nearest ten. The unit before the tenth digit is 9, hence 9 would be rounded up to 1, and then added to the tenth digit, which is 8 to give 9.

Hence the answer is 90
