What number is 25% of 20?

5

Step-by-step explanation:

For this problem, we can solve this by simply converting percentages into fractions.  Consider that 25% is 1/4 of 100% of 1.  Therefore, we can say 25% is equivalent to 1/4.

With this statement, we can say the following:

25% of 20

= (1/4) of 20

= (1/4) * 20

= 20 / 4

= 5

So 25% of 20 is 5.  Using this property of fractional equivalence, percentages can also be stated in reverse.

For example, 25% of 20 is equivalent to 20% of 25.

Since we know 25% of 20 is 5, let's use the same fractional equivalence to find the value of 20% of 25:

20% of 25

= (1/5) of 25

= (1/5) * 25

= 25 / 5

= 5

Thus, we have shown that 25% of 20 and 20% of 25 are equivalent.  This applies to all percentages of some number.

Hope this helps.

Cheers.

step-by-step explanation:

strong negative correlation

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
