Question

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

Answer 1

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

Answer 2

4 1/4 - 1 3/9
= 3 1/4 - 1/3
= 3 3/12 - 4/12
= 3 - 1/12
= 2 11/12
