Erin buys a bag of peanuts that weighs \(\frac{3}{4}\) of a pound. Later that week, the bag is \(\frac{2}{3}\) full. How much does the bag of peanuts weigh now?
Answer (2)
In math, "of" usually means "times".
2/3 x 3/4 = 6/12 = 1/2 pound .
The bag of peanuts now weighs 2 1 of a pound. This is calculated by multiplying the initial weight of the bag, 4 3 of a pound, by the fraction it is currently full, 3 2 . Thus, the weight is 4 3 × 3 2 = 2 1 pound.
