year 5 howework help?

How would you do this:
I have £76 to spend on Christmas presents. If I find an item costing £17.65, how many can I buy?

Obviously I would do £76/£17.65 but dc never done division with decimals, so I'm kind of stuck??

Keep adding 17.65 until you go over

Show him it's the same? Just keep the decimal where it is throughout of change everything in to pence.

*or

Get them to round the decimal.

Or if they are comfortable with long multiplication then that with a bit of trial and error (should be able to estimate reasonably close)

Round up to 18 and estimate. 4x18 is £72 so he won't be able to buy more than 4.

Try plausible estimation, then check.

£17.65 is a bit under £20, and £76 is a bit under £80.

Can DC see what to do to with the numbers when both rounded up?

So try multiplying by 4 and see what happens.

A bit odd to be having a Christmas themed maths problem at this time of year misses the point

Any of the methods above would be acceptable.

For a child I would do it as repeated addition. I would suggest finding out how many 2, then 3 would cost until you get within £17.65 of £76. Alternatively would your DC understand rounding to £18 and then repeating the above method?
As an adult I estimate that's close to £20, £2.35 less. £76 is almost £80, so likely to be 4 presents, check that 4x£2.35 is more than £4 (£80-£76).
Hopefully something in one of these methods will be familiar to your DC, good luck!

Can he do long division? If yes, get him to change it all into pennies,so 7600 divided by 1765.
If not repeated addition,or estimates. It might be helpful to ask what he did in school,as it might be linked if a specific method is needed.
