This Multiple Ratio problem is complicated by the fact that the number of rubies is not consistent between the two given ratios, appearing as 2 in one and 3 in the other. You can use the least common multiple of 2 and 3 to make the number of rubies the same in both ratios:
E:R:S E:R:S
1:2 multiply by 3 3:6
3:5 multiply by 2 6:10
Combining the two ratios into a single ratio yields:
E : R : S: Total = 3 : 6: 10 : 19
The smallest possible total number of gemstones is 19. Therefore, Quantity B is greater.
