Nadia charges $7.50 an hour for babysitting. she babysits 18.5 hours the first week of the month and 20 hours the second week of the month. to find her total earnings for those two weeks nadia writes 7.5 x 18.5 + 20 = $158.75, explain her error show the correct solution.

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.
