I went shopping once for ingredients of a cake, but i didn't know what my finale price would be. So i estimated what the total cost could be, then i took all the prices and added them up then divided the price by how many ingredients i got to find the average and it was pretty close to my estimate. So math can help when you go shopping. (Sorry if how i find my prices is weird, i kinda just stand in one spot for at least 5 - 8 mins trying to find my price)

Answer:
18 plastic propellers, 18 Bug Antenna, 24 moose antlers,
Step-by-step explanation:
When we multiply our total sum of 60 by certain decimal values by converting the factions to decimals we can get each type of hats count.
1/3 works out to be 0.30
60×0.3 = 18
2/5 works out to be 0.40
60×0.4 = 24
To find out the remaining amount that is plastic propellers you subtract the added hats and the total value.
60 - (18 + 24)
60 - 42
18
