Answer:
40
Step-by-step explanation:
Least common multiple (LCM) of 8 and 10 is 40.
8: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80
10: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100
Common Mutiples: 40 and 80
LCM: 40
12.5%
sum the parts of the ratio 1 + 3 + 4 = 8 parts
8 parts represents 100%, hence
1 part = = 12.5% ← Andy's percentage of the total
If rounded up by the nearest whole number, it'd be 210, because it isn't using the decimal numbers, and the whole number would get the boot, meaning only 200 and 10 would remain. Please let me know if this helped.
