Question

Please help me with these two question​s

Answer 1

first take LCM that is 21

-15/21. and. -14/21

these numbers are not enough so take equivalent fraction

-30/42. and. -28/42

now also it is not enough

so it becomes

-60/84. and. -46/84

so required answer is

-47/84

-48/84

-49/84

-50/84

-51/84
