LCM of 10,-15,20,-30 is 60
Now make all the denominators 60
Like you have to make 10 =60 so you have to multiply it by 6
You need to write it as -3/10*6
You need to multiply with both
Like this you need to make all the denominators 60
And then you will get your answer
The answer is as same as the question
