Question

ch decimal Q1 simplify the following a) 1/8+7/12+[-2/9]​

Answer 1

Answer:

The result is 35/72.

Step-by-step explanation:

To add rational number with the same denominator, we need to take the the LCM of the denominator to make all the denominators same.

The LCM of 8, 12 and 9 is 72.

1/8 x 9/9 = 9/72

7/12 x 6/6 = 42/72

[-2/9] x 8/8 = [-16/72]

Add all the numbers.

9/72 + 42/72 + (-16/72)

It becomes, (9+42-16)/72

By adding we get, 35/72.

Therefore that is the answer.
