In a recent survey 5 out of every 8 middle school students use a computer to complete school projects. franklin middle school has 520 students. how many are expected to use computers

You have to make a proportion:

needs to be set equal to  \frac{x}{520}[/tex] because it is equal to the 5:8 ratio

Then cross multiply to solve for x:

520 × 5 = 2,600

8 × x = 8x

^^^set those equal to each other and solve for x

2,600 = 8x

^^^to isolate x divide both sides by 8

(2,600 ÷ 8) = (8÷8)x

325 = (1)x

325 = x

325 students out of the 520 students that attend the middle school use computers

Hope this helped!

55% are girls and 45% are boys : ) hope this
