Answer :
So we want to know how many students out of 144 practice martial arts every day if we know that 7/12 practice every day. So lets multiply the numerator and the denumerator with 12. We will get (12*7)/(12*12)=84/144. And we got our answer: 84 out of 144 students practice every day.
Answer:
84 students out of 144 students practice everyday.
Step-by-step explanation:
Marissa is researching information martial art students, she found that 7 out of 12 martial artist practice everyday.
First we will find the percentage of the sample research.
[tex]\frac{7}{12}[/tex] × 100
= 58.33%
There are 144 martial arts students, so we calculate 58.33% of total students.
[tex]\frac{58.33}{100}[/tex] × 144
= 0.5833 × 144 = 83.995 ≈ 84 students.
84 students out of 144 students practice everyday.
