Question

Add :

(ii) 5/-9 and 7/3​

Answer 1

Answer:-

Firstly we need to convert the denominators to positive numbers.

5/-9 = (5 × -1)/ (-9 × -1) = -5/9

The denominators are 9 and 3

By taking LCM for 9 and 3 is 9

We rewrite the given fraction in order to get the same denominator

-5/9 = (-5×1) / (9×1) = -5/9 and

7/3 = (7×3) / (3×3) = 21/9

Since the denominators are same we can add them directly

-5/9 + 21/9 = (-5+21)/9 = 16/9

Answer 2

Answer:

16/9

Step-by-step explanation:

-5/9+7/3

by taking 9 as lcm

(-5+21)/9

16/9
