Question

How many halves are in 11 1/2

Answer 1

I got 11.5 

Hope this helps

Answer 2

Well you could ask yourself how many halves are in 1. And there are 2 halves in 1. so that means you could now say that for ever 1 whole number there are 2 halves.

next you ask yourself what if I have 2 whole numbers. well you can say now you have 2 whole and 2 halves for each whole. this means 1 * (2 halves) + 1 * (2 halves) = 4 halves.

we could do this all the way up to 11 and 1 half but there is something to notice. If if you have 2 whole and 2 halves for each whole this translates to 2 * (2 halves) = 4

see how they end up being the same answer but this one can be written much easier when dealing with larger numbers like 11.

so we can say:
11 wholes * (2 halves) = 22 halves

But but don't forget the extra 1/2 from 11 and 1/2

so the answer after adding the last one in is 23 halves
