1/7 gallon = 1 batch
<em>[multiply by 7 through]</em>
1 gallon = 7 batches
<em>[multiply by 8/9 through]</em>
8/9 gallon = 7 x 8/9
8/9 gallon = 6 2/9
<em>[Good enough to make 6 batches, not enough to make 7 batches]</em>
So he can make 6 batches of collard green
14+2x=4x: divide 2x on each side
14=2x: divide by 2
7=x
7
Let B = age on Ben
and age of Ishaan =I
B =4I
B = 6+I
Gives 6+I = 4I
6 = 3I
I =2 years and B = 4x2 = 8years
Age of Ishaan = 2 years
I got 16.8 , but she’ll need roughly 17 gallons of paint :)
how i did it :
1. so you know she’ll need 4/5 per book case, and there are 16 bookcases.
2. So you do 16 x 5, then you get 84
3. and you divide 84 by 5. and you’ll get 16.8, that’s how many gallons of paint she needs
