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.

× 100

= 58.33%

There are 144 martial arts students, so we calculate 58.33% of total students.

× 144

= 0.5833 × 144 = 83.995 ≈ 84 students.
