The number of students at marita`s school decreased to 90% of last year's number. last year, there were 1,500 students. how many students are there this year

1350

Step-by-step explanation:

We can write a proportion to find the total amount in the school this year using the information given. A proportion is two equivalent ratios set equal to each other. If 10% has decreased, then 90% is now left.

We will cross multiply the numerator of one ratio with denominator of the other. And then solve for y.

10(1500)=100(y)

15000=100y

y=150

Y is the number of students who are now gone. We subtract 1500-150=1350

i got 10.28 but that rounds up to 10.3
