e.g. If 31hours 36 minutes is 31.60 expressed as a decimal (is that right?!), then what is 24hours 24minutes as a decimal? And what is 4hours 52minutes? A simple sum so I can work it out would be great!!

Devide the minutes by 60 and that is the decmial so 30 minutes diveded by 60 is half or in decimal 0.50

Remember that fractions and decimals are different ways of expressing a quotient, and a quotient is the result of a division problem. For example,
1÷2 = ½
and
1÷2 = 0.5
so
½ = 0.5
Same value, different form. ½ is converted into decimal by using long division.
------------------
To express 36 minutes as a fraction of an hour,
36 minutes * (1 hour/60 minutes) = 36/60 hour
Notice how the minute units cancel out, leaving the answer expressed in hours. After doing the long division you get
36 minutes = 0.60 hour
Do the same for 24 minutes:
24 * (1/60) = 24/60 = 0.4
Do the same for 52 minutes:
52 * (1/60) = 52/60 ≅ 0.87

Hours + Minutes/60
For example:
31 + 36/60 = 31 + 6/10 = 31.6
Or:
24 + 24/60 = 24 + 2/5 = 24.4
Now you try it:
4 + 52/60 = ??

there are 60 mins per hour, so just divide the number of minutes by 60 and get the decimal equivalent, so 4hrs 52 mins = 4+52/60=4.8667 hrs

the decimal is the number of minutes divided by 60 :)
so 24 hours 24 minutes
is 24 hours and...
24/60 = 0.4
so 24 hours 24 minutes is 24.4 hours

in this case think of the decimal as a percentage that you're looking for. Take the part you're looking for divided by the whole, so take your minutes / 60[the whole] and you'll get your answer.
Hope this helps!!

divide the seconds by 60 and add them to the minutes
then divide that result by 60 and add them to the hours
(Keep it simple)
