The ratio from girls to boys is 4 to 5 in Hopkins middle school if there are 310 girls how many total students are there

388 (approximately)

Step-by-step explanation:

So basically look at this as a fraction

if the ratio is 4 to 5 you could set the fraction as 4/5

So to get the answer, find out what you multiply to 4 by to get 310, to do this, divide 310 by 4.

310/4 = 77.5

Now multiply 5 by 77.5 to get the amount of boys.

You get 387.5, round that up to 388, (since you can't have a fraction of a person).
