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: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.
