Erin buys a bag of peanuts that weighs 3/4 lb later that week the bag is 2/3 full. How much does the bag of peanuts weigh now?
the bag decreased one third, so its weight decreases the same, so:
3/4pound - 3/4 pound*1/3
=3/4pound - 1/4 pound
=2/4 pound
=1/2 pound
To find out how much the bag of peanuts weighs now, we need to calculate the weight of the remaining peanuts.
Firstly, we can calculate the weight of the peanuts that are still in the bag. We know that the bag is 2/3 full, which means there is 2/3 of the original weight of the peanuts remaining.
To calculate this, we multiply the original weight of the peanuts by 2/3:
(3/4 lb) * (2/3) = (6/12 lb) = (1/2 lb)
Therefore, the bag of peanuts now weighs 1/2 lb.
