Question

There are 680 raisins in 8 bags. If each bag has the same number of raisins, how many raisins are in 12 bags?​

Answer 1

1020 raisins

Explanation:

Let's set up a proportion using the following setup:

raisins/bags= raisins/ bags

We know there are 680 raisins in 8 bags.

680 raisins/8 bags= raisins/bags

We don't know how many raisins are in 12 bags, so we can say x raisins are in 12 bags.

680 raisins/ 8 bags= x raisins / 12 bags

680/8=x/12

We want to find x. To do this, we must get x by itself.

x is being diveded by 12. The inverse of division is multiplication. Multiply both sides of the equation by 12.

12*(680/8)= (x/12)*12

12*680/8=x

12*85=x

1020=x

x= 1020 raisins

There are 1020 raisins in 12 bags.
