By taking the product between fractions, we can see that the friend bought (4 + 29/40)lb
How many pound of grapes bought the friend?
The friend bought 3/8 of (12 + 3/5) lb of grapes.
So we need to take the product between these two numbers, we will get:
G = (3/8)*(12 + 3/5) lb
G = (36/8 + 9/40) lb
Now we multiply and divide the first fraction by 5 so we have the same denominator:
G = (180/40 + 9/40) lb
G = (189/40) LB = (160/40 + 29/40)lb = (4 + 29/40)lb
Then we conclude that the friend bought (4 + 29/40)lb of grapes.
