a=45

Step-by-step explanation:

a/15 + -6+9

a/15=3

2=45

A = 45

Step-by-step explanation:

SIMPLIFY -6 + 9 TO 3

A/15 + 3

MULTIPLY BOTH SIDES BY 15

A + 3 X 15

SIMPLIFY 3 X 15 TO 45

A = 45

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.
