Your mum has saved £12,000 and has agreed to give you a share. would you rather have 1 5 or 1 10 ?

I think everyone would rather have 110. I don't really get your question, but i guess most ppl would want the larger amount of money

Do you possibly mean 1/5 and 1/10?
If so, (if you wanted more money) you would choose 1/5.
Explanation: To compare both fractions it is wise to give them both the same denominator (bottom number). We can see that 5 is half of 10. To make the 5 equal a 10, we would need to multiply 1/5 by 2. Remember that you need to multiply the 1 (numerator) as well.
That gives 2/10.
This process can make it easier to see that 2/10 is larger than 1/10.

I hope I interpreted your question right :)

The answer would be 484
