Question

Ross took a science test and got 25 questions correct and 8 questions incorrect. What was the percentage of answers he got correct? Round the answer to the nearest tenth.

a 75.8
b 32.0
c 24.2
d 68

Answer 1

a. 75.8

Ross got a 75.8% on his science test.

Explanation:

If Ross got 25 right and 8 wrong, there must be 33 questions on the test over all. (25+8=33)

He got 25 out of 33 correct,

25/33.

You divide 25÷33 which gives .757575

Convert to a percent by multiplying by 100 or moving the decimal point two places to the right.

So Ross got 75.8% correct on the science test.
