Answer:
1020 raisins
Step-by-step 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.
You have to make them have their least common denominator to add or subtract, in this case 36.
Multiply 1/12 by 3, to get the denominator 36: 3/36.
Multiply 7/9 by 4, to get the denominator 36: 28/36.
Now add the numerators: 3+28=31, 31/36 is as simplified as possible so your answer is 31/36 :) I hope this helps :)
