Question

Mr. Brown shares with the class that 70% of the students got an A on the English vocabulary quiz. If Mr. Brown has 100 students, create a model to show how many of the students received an A on the quiz.

a. What fraction of the students received an A on the quiz?
b. How could we represent this amount using a decimal?
c. How are the decimal, the fraction, and the percent all related?

Answer 1

a.
`(70)/(100)`

b. 0.7

c. 0.7=70%=
`(70)/(100)`

Explanation:

70% of 100 received an A, that is 70/100 times 100 equal to 70

`(70)/(100)*100=70`

a. 70% =
`(70)/(100)`

b.
`(70)/(100)` = 0.7

Notice that 70/100 is equal to 7/10 which is 0.7

c. 0.7=70%=
`(70)/(100)`
