Question

HELP ME PLEASE!!! i cant do this and it is due in 10 minutes.

25% of 7th grade classrooms are math classrooms. The 7th grade area has three math classrooms. How many classrooms are there in the seventh grade area?

Answer 1

• 12 classrooms

Explanation:

25% of classrooms is 3, find 100%

• 25% ⇒ 3
• 100% ⇒ x

Since 100% is 4 times 25%, the corresponding number will also be 4 times greater:

• x = 4*3 = 12
