Approximately how many time greater is the amount of earth surface that is covered by water compared to the amount of earth of earth surface that is covered by land?

The amount of the earth’s surface covered by water is 2.12*10^8 greater than the amount of the earth’s surface covered by land.

Step-by-step explanation:

(Subtraction of scientific notation)

Earth’s surface covered by water- 3.61*10^8

Earth’s surface covered by land- 1.49*10^8

(3.61*10^8) - (1.49*10^8)

(3.61-1.49) *10^8

2.12*10^8

Hope this helps you out

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.
