Question

A baker bought 680,000 oz. of flour and packed the flour into 200 bags of equal size. He used some flour and had 100 bags left. He decided to repack the remaining flour bags into bags of 5,000 oz. bags. How many bags of flour did he have in the end?

Answer 1

If he used 100 bags of the flour, this means he used 1/2 of the flour (100 is 1/2 of 200). So, 1/2 of 680000 is 340000 oz that were left. Therefore, he had 340000/5000 bags (you can do the math).
