There are 480 students in Sara’s school. If 70% of

the students participate in the fundraising program,

how many students participate in the

fundraising program?

Now solve: s 480

___ =

100 • s = 70 • 480 100s = 33,600100s 100

____ 33,600 100

_____ = s = 336

Let s represent the number of students who participate in the fundraising program.The cross products are equal.s is multiplied by 100.Divide both sides of the equation by 100 to undo multiplication.

Since 336 is close to your estimate of 375, 336 is a reasonable answer.336 students participate in the fundraising program.
