Question

-4/9+-5/-6 step by step explanation
Please answer this by Doing LCM method for denominators​

Answer 1

Answer:

-4/9 + -5/-6

Step-by-step explanation:

1st

cancel the minus of 5/6

because the minus will cancel off itself

2nd

-4/9 + 5/6

now how to take LCM..?

find the lowest no. that comes in both 9 and 6 for example 18. The lowest that comes in both 9 and 6 is 18 therefore, LCM is 18

3rd

take the no. with which we can multiply 9 so that it becomes 18 on multiplying 9 with 2 we can get 18 and same for 6 in the table of 6 we know when 6 multiplied by 3 we get 18 .

4th

now multiply both denominator and numerator with the no. like in the above question

-4*2/9*2 + 5*3/6*3

-8/18 + 15/18

5th

now the denominators become same now simply add numerator.

-8 + 15 /18

7/18

therefore, the answer is 7/18.

hope it helps
