Please show me working out for 4 1/4 - 1 3/9

Question

anonymous · Answer

convert them to improper fractions first
oh you can simplify the second one  - it same as 1 1/3
4 1/4  =   17/4 and 1 1/3  = 4/3

17    -      4
--            --
4              3

now you need to make the bottom parts (denominators) equal  by 
finding the lcm (lowest common multiple)  of 3 and 4 which is 12
so the sum becomes
51  -      16                 35
--           --   =           --    
12           12                12

answer is 35/12  or   2 11/12
