Question

Adam has 12 bags of pumpkin seeds that each weigh 3/8. How many ounces of pumpkin seeds does he have in all? / What is the total weight of all 12 bags?

Answer 1

Adam has 4 1/2 or 4.5 ounces of pumpkin seeds.
To find the answer you need to multiply 12 by 3/8 because the word each means multiplication
So 12*3/8=12/1*3/8 because to multiply whole numbers by fractions you first need to convert 12 into a fraction so 12 as a fraction is 12/1.Next you multiply across so you will end up having 36/8.Then you can reduce 36/8 and you will end up having 9/2.(you simplify by looking at which number could go into 36 and 8 and in this case it would be 4 then you have to divide 36 and 8 by 4).
Finally you convert 9/2 into a mixed number and you will end up with 4 1/2.(you convert an improper fraction into a mixed number by dividing the numerator by your denominator).

Answer 2

4.5 ounces.. 12x3/8=4.5
