Robert writes a check for $20. When he records the check in his check register, he accidentally adds $20 to his balance instead of subtracting $20, which causes a
discrepancy between what Robert's check register shows and what it should show.
Because of his mistake, Robert's check register shows:

cheese

Step-by-step explanation:

cheese

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.

i think it might be a but you might want a second opinion
