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
