Question

9 1/2 - 4 3/4

Answer 1

ok, so I like to change everything into proper fractions first of all.


so 9+1/2 becomes 19/2
and
4+3/4 becomes 19/4

so we need a common denominator of 4.

so 19/2 becomes 38/4

38/4-19/4

it becomes 19/4 or 4+3/4

Answer 2

9 .....1/2--> 2/4
4 ......3/4-->3/4
---------
......you cant subtract 3/4 from 2/4 so you have to borrow. Take one (4/4)away from 9 and add it to 2/4. This makes the problem...
8 6/4
4 3/4
------subtract
4 3/4
