If 20 is decreased by 40%, what is the new amount?

The correct answer is 12.

Step-by-step explanation: If 20 is decreased by 40% the first thing that we need to do is calculate how much is 40% of 20.

20 x .4 = 8

Now, subtract 8 from 20:

The

20 - 8 = 12

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.
