Question

The zookeeper had a huge bottle of the animals’ favourite liquid treat, Zoo Cola. The monkey drank 15 of the bottle. The zebra drank 23 of what was left. How much of the bottle of Zoo Cola did the zebra drink?

Answer 1

60.5% was the amount the zebra drank

Explanation:

The bottle in total is 15+23=38 units

To get the % for the zebras portion you divide 23 by 38 which equals roughly 0.605 or 60.5%

edit: 1/5 of 100% is 20% which leaves 80%, 2/3 of the 80% thats left is 53.3333%

so you divide 1 by 5 which equals 0.2 or 20%, which leave 80%, then you divide 2 by 3, which equals 66.6666%, times that by the 80% (0.80 x 0.666666) equals 0.533333 or 53.333%

Therefore the Zebra drank 53.333% of the bottle
