A bag of fertilizer weighs 6 1/2 Ib. How much does 1 1/3 bags of fertilizer weigh?

Answer 1

First one full bag would weigh 6 1/2 lbs. You need to determine how much 1/3 of a bag would weigh and then add it to the weight of one bag:

1/3 of 6 1/2 = 1/3 * 6 1/2 = 1/3 *13/2 = 13/6 lbs

13/6 lbs is equal to 2 1/6 lbs (for one third of a bag)

So the weight of of 1 1/3 bags would be: 6 1/2 + 2 1/6 = 6 3/6 + 2 1/6 = 8 4/6 lbs or 8 2/3 pounds
