Your answer is 1/16
(X×6)/6 =3/8
(X×6)/6 =(3/8)/6
I’m pretty sure the answer is -237, -236, -235, and -234. Because -234 would be the greatest of that consecutive set.
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.
