Question

Laura got \[84\%\] of the 150 test questions right. How many correct answers did she have?

Answer 1

Hint: We are given that Laura got \[84\%\] of the 150 test questions right and based on this we have to find the number of answers Laura got correct. To find the number of questions using the percentage, we will convert the percentage into a fraction first and then multiply the obtained fraction by 150. So, \[84\%\] will mean that \[\dfrac{84}{100}\] and we will multiply this fraction with 150 and the resulting answer will be the number of correct questions Laura did.

Complete step-by-step answer:
According to the given question, Laura got \[84\%\] of the 150 test questions right. We are now asked to find the number of questions that Laura did correctly using the given information.
The total number of questions asked in the test is 150.
Laura got \[84\%\] of the test questions right.
To find the number of correct questions, we will first have to express \[84\%\] as a fraction.
We get,
\[84\%\] will mean \[\dfrac{84}{100}\].
Now, we will multiply the obtained fraction with 150 to get the number of questions Laura did correct.
Multiplying the fraction with 150, we get,
\[\dfrac{84}{100}\times 150\]
Multiplying the numerator with 150 we get,
\[\Rightarrow \dfrac{12600}{100}\]
Dividing the resultant by 100, we get the value as,
\[\Rightarrow 126\]
Therefore, the number of questions that Laura did correct is 126.

Note: The question has a slight confusing tone, so while reading the question understand the question as to what exactly is asked in the question. The multiplication should be done correctly and make sure that the percentage given is equivalent to the fraction that we wrote.
