Olivia is 4 feet 10 inches tall. she compared her height with her younger sister, susan, and found that susan is 15 inches shorter than she is.
what is olivia's height, in inches?
what is olivia's height, in centimeters?

the answer is 8

step-by-step explanation:

3.14 x 8x8

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
