One grain of this sand approximately weighs 7 x 10^-5g. how many grains of sand are there in 6300 kg of sand

6.3 x 106 ÷ 7 x 10-5 = 0.9 x 1011 or 9 x 1010

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.
