To find the percent of a number, you multiply the percent in decimal form and the number.Therefore 45% of s is 0.45s.
If 45% of s is 18, then 0.45s=180. Since 0.45=45100=920, then 0.45s=18 can be rewritten as 920s=18.
To solve for s, you then need to multiply both sides of the equation by 209, which gives:
209×920s=209×18
s=209×18 Simplify
s=40Multiply
Therefore, 45% of 40 is 18.
