2/9 of the students are in sixth-grade a. How many sixth graders are there if the school has 90 students?

b. How many sixth graders are there if the school has 270 students?

a. 20

b. 60

Step-by-step explanation:

For this problem you could want to multiply 2/9 and 90, to get the first one, and the second one by doing 2/9 times 270, and since 270 is 3 times as much as 90, you could just multiply your first answer by 3.

hope this helps!

19.8/90

59.4/270

Step-by-step explanation:

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
