Question

Olivia is using 160 quilt squares to make a red, yellow, and blue quilt. If 25% of the quilt squares are red and 30% are yellow, how many quilt squares are blue?

Answer 1

72 blue quilt squares

Explanation:

Total number of quilt squares = 160

Percentage of no. of red quilt squares = 25%

Percentage of no. of yellow quilt squares = 30%

So, percentage of no. of blue quilt squares = 100 - (25 + 30) = 45%

No. of blue quilt squares =
`(45)/(100) *160=(45*160)/(100) = (7200)/(100) =72`
