Question

emma got 90% of the questions on her math test correct. if she answered 36 questions correctly, how many questions did emma get wrong? drag the answers into the boxes to correctly complete the sentence. there were □ questions on the test, so emma got □ questions wrong.

Explanation:

Step1: Find total number of questions

Let \( x \) be the total number of questions. We know that 90% of \( x \) is 36. So, \( 0.9x = 36 \). To find \( x \), we divide both sides by 0.9: \( x=\frac{36}{0.9}=40 \).

Step2: Find number of wrong questions

Total questions are 40, correct are 36. So wrong questions \( = 40 - 36 = 4 \).

Answer:

There were \( \boldsymbol{40} \) questions on the test, so Emma got \( \boldsymbol{4} \) questions wrong.
