Question

In a group of hats consisting of only blue hats, green hats, and purple hats, the ratio of blue hats to green hats to purple hats is 7:4:12. If there are a total of 92 hats in this group, how many of these hats are not blue

Answer 1

Answer:64 hats

Step-by-step explanation:

Ratio of Blue hats= 7

Ratio of Green hats= 4

Ratio of purple hats= 12

Total ratio = 7+4+12 = 23

Total hats= 92 hats

To get number of hats.that are not blue, we add the ratio of green and purple together= 4+12= 16

Number of hats that are not blue will be:

16/23 × 92

= 16 × 4

= 64

64 hats are not blue.
