Question

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

Answer 1

520/8 = 65

5 • 65 = 325

65 • 8 = 520

The answer is 325 students hope this helps!

Answer 2

You have to make a proportion:

`(5)/(8) = (x)/(520)`

`(5)/(8)` 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!
