If 100 students make up 40% of the 6th grade population, then 50 students make up 20% of the 6th grade population. 20% × 5 makes 100% so if your multiply 50 by 5 you'd get your population.
50 × 5 = 250 sixth-graders

Answer:

250

Step-by-step explanation:

You can solve this by cross-multiplication.

If one hundred sixth-grade students represent 40% of the total, you need to find the 100% so, multiply 100% by 100 students and then divide by 40% and you'll have the total sixth-grade students.

40%----100

100%--x=

$X=(100*100)/40\\X=250$
