Step-by-step explanation:
Ahmed:
60% = 3/5
3/5 x 30 = 18
therefore out of 30, 18 are toffees.
30 - 18 = 12
therefore 12 are chocolates
Ben:
3/8 x 40 = 15

Answer:
5.2 Minutes, or 5 minutes and 12 seconds
Step-by-step explanation:
You can solve this problem by working backward. Since our number gets smaller by a 1/10 or 0.1, in order to work backward we must multiply 3.60 by 10/9, since one tenth has been taken away already. When we do this, we get 4.0. When we add 1.2 minutes to that, we get a final answer of 5.2 minutes, or 5 minutes and 12 seconds.
