What percent of 180 is 45? A. 4.5% B. 18% C. 22% D. 25%

Answer 1

Hi there! :)

Answer:

The answer is D. 25% of 180 is 45.

Step-by-step explanation:

Let's replace "what percent" with the letter "x" because it's what we are looking for.

The word "of" is the same thing as a multiplication sign, which means that the sentence "What percent of 180 is 45?" can turn into "x times 180 is 45".

The word "is" is the same thing as an equation sign, wich means that you can write this as an equation:

x × 180 = 45

180x = 45

Now all you have to do is solve this equation by isolating "x" to find your answer:

180x = 45

Divide each side of the equation by 180 → 45 ÷ 180 = 0.25

x = 0.25

0.25 = 25 ÷ 100 = 25%

There you go! I really hope this helped, if there's anything just let me know! :)
