Question

Colin and Dan are marking exam papers. Each set takes Colin 23 minutes and Dan 1 hour. Express the times Colin and Dan take as a ratio in its simplest form

Answer 1

Answer:

Time taken by Colin = 23 minutes

Time taken by Dan = 1 hour = 60 minutes

Hence, ratio = 23 : 60

HCF of 23 and 60 = 1. Therefore, 23 : 60 is in its simplest form.
