Question

Robin donated bags of grain that each weighed 40/3 pounds to the local food shelf. If the total weight of the grain was 160 ponds, how many bags of grain did Robin donate

Answer 1

we know that

each bag of grain weighed 40/3 pounds
so

if 1 bag of grain weighed----------> 40/3 pounds
 X bags-----------------------------> 160 pounds
X=160/(40/3)----> x=160*3/40----> 12 bags

the answer is
12 bags

Answer 2

Answer:

12 bags

Step-by-step explanation:

If the total weight was 160 pounds and each bag weighs 40/3 pounds, we need to divide the total weight between the weight of each bag in order to know how much each bag weights.

$\frac{160}{\frac{40}{3} } =\frac{(160)(3)}{40} =\frac{480}{40} = 12$

Therefore, the total number of bags of grain that Robin donated is 12.
