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?

30 blue pins

Step-by-step explanation:

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

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

100 x

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

30 times 1 is 30

there are 30 blue pins

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
