Eva wanted to fill bags with 3/4 pounds of trail mix. she started with 11 3/8 pounds but ate 1/8 pound before she started filling the bags. how many bags could she fill

11 and 3/8-1/8=11 and 2/8=11 and 1/4

3/4 times xbags=11 and 1/4
convert 11 and 1/4 to improper faction
11 and 1/4=11+1/4=44/4+1/4=45/4

3/4 times xbags=45/4
times both sides by 4/3 (to clear fraction since 3/4 times 4/3=12/12=1)
xbags=180/12
xbags=15

she could fill 15 bags

So first you subtract 1/8 from 11 3/8 and you get 11 1/4. Then you turn it into a mixed number which is 45/4. Then you divide that by 3/4 which is just multiplying it by it's reciprocal. The answer is 180 over 12 which is simplified to your final answer 15.

The correct answer is: 2
