3- 1/2 X 7/5

10/3 X 1/7

7/5 X 7/5

1/2 X 4/5

Answer 1

5/3 - 1/2

MMC (2, 3) = 6

10/6 - 3/6
=> 7/6

------------------------

5/6 + 7/3 - 1/2

MMC (6, 3, 2) = 6

5/6 + 14/6 - 3/6
19/6 - 3/6
16/6 (÷ 2)
8/3

-------------------------

3 - 1/2 . 7/5
3 - 7/10

MMC (1, 10) = 10

30/10 - 7/10
=> 23/10

-------------------------

10/3 . 1/7
=> 10/21

-----------------

7/5 . 7/5
=> 49/25

----------------------

1/2 . 4/5
4/10 (÷ 2)
=> 2/5
