Quick divide and give the answer in scientific notation. 8.4 x 10^7 3 x 10^3 a) 5.4 x 10-4 b) 5.4 x 1021 c) 2.8 x 10-4 d) 2.8 x 104

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.

a is the correct
