Question:

Victoria took a test and got 80% of the questions right. She answered 20 questions correctly. How many questions were on the test?
Options:
20
22
25
28

Answer 1

Answer: 25

Explanation:

80/ 100 = 0.8

20/? = 0.8

= 20/0.8 = 25

Answer 2

Another way of asking this question would be... "20 is 80 percent of what number"?
80/100 = 20/x
reduce to lowest terms...
4/5 = 20/x
this makes it a little easier to figure out...
Divide 20 by 4, then multiply by 5 to get 25. There were 25 questions on Victoria’s test!
