12 grapes cost 90 $how many can bought in 40$
likoan [24]

Let x = the amount of grapes that can be bought for 0.40.


Note: By 90 I assume you mean 90 cents. The same for 40.


12/x = 0.90/0.40


0.90x = 12(0.40)


0.90x = 4.80


x = 4.80 ÷ 0.90


x = 5.33333


We can round the decimal to the ones place to get 5 grapes.
