The type of part being manufactured today should be 1.27 inches wide, with a tolerance of 0.04 inches. If a part does not meet the size requirement, it must be rejected. You have 4 parts to inspect. They have the following widths. How many must be rejected? 1.275 inches, 1.300 inches, 1.266 inches, 1.255 inches

The range of widths is {1.23,1.31} so none will be rejected, answer A.

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.
