Let us assume the unknown number to be = x
Then
(20/100) * x = 18
x/5 = 18

Answer 2
Answer:

The number represented by 20% of 18 is 90.

To find out what number is represented by 20% of 18, set up an equation.

Let "x" be the unknown number  are trying to find.

The word "of" in mathematics typically indicates multiplication. So, "20% of x"  represented as 0.20 × x or simply 0.20x.

Now, the problem states that 20% of this unknown number (0.20x) is equal to 18:

0.20x = 18

To find the value of "x," to isolate it on one side of the equation. To do that, divide both sides of the equation by 0.20:

x = 18 ÷ 0.20

x = 90

During 2002 a town had a total snowfall of 92 inches, which was an increase of 15% from the previous year. What was the total snowfall in the previous year?

Answers

1.) Divide 92 by 100 so that it can be 100 pieces or 100%  92/100= 0.92
2.) Multiply the 15% be 0.92 to get how much more inches in snow that they got this year than last year.  15 X 0.92= 13.8
3.) Since we have how much more inches of snow they got all we need to do is subtract 13.8 from 92.   92-13.8= 78.2
4.) In the previous year the town had received 78.2in of snow.
