Question

Kendra ordered a set of blue and brown pins. She received 100 pins, and 30% of them were blue. How many blue pins did Kendra receive?

Answer 1

30 hair pins were blue

Explanation:

100 x 0.3 = 30

Answer 2

30 blue pins

Explanation:

30% is the same as 30 out of 100, so this can be written in this fraction:
`(30)/(100)`

now, you should multiply this fraction by the total number of pins she ordered:

100 x
`(30)/(100)`

to solve this, you can simplify by dividing 100 by 100, this equals 1

30 times 1 is 30

there are 30 blue pins
