This equation has 2 solutions.
1. 
2. 
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.
1060.5263157 etc your teacher prob tells you to round
Answer:
A( multiply both sides by 6)
As seen , the L.C.M is 6 so to do away with the fractional form, we will multiply by 6
