Answer:
The weight of the remaining rice is 102/7 (or 14.57)
Explanation:
Weight of 1st bag = 50/6 = 25/3
Weight of 2nd bag = 128/3
So,
Total weight = weight of 1st bag + weight of 2nd bag
Total weight = 25/3 + 128/3
Total weight = 153/3
Total weight = 51
If 5/7 of the total weight is sold, the remaining weight is then
1 - 5/7 = 2/7
2/7 of the total weight remains, which is,
2/7 of total weight = (2/7)(51) = 102/7
So, the weight of the remaining rice is 102/7
