One hour is made out of 60 minutes. Hence to convert the minutes into hours, you have to divide them by 60. For example, 225 minutes = (60 + 60 + 60 + 45) = 3 hours 45 minutes.
'0' is also a number, so if the answer includes 0 hours or 0 minutes, you must type it into the box provided. Please don't type your answers into the grey boxes. Remember not to type in any space into your answers, else they will be marked wrong. When you are done, click on Score Me. Repeat the exercise until you get 100%.
