Question

Subtract the sum of -7/8 and 5/16 from the sum of 3/5 and 2/9​

Answer 1

Answer:

997/720

Step-by-step explanation:

1. 3/5 + 2/9 (LCM = 45)

3/5 * 9/9 = 27/45

2/9 * 5/5 = 10/45

So, 27/45 + 10/45

= 37/45

2. -7/8 + 5/16 (LCM = 16)

-7/8 * 2/2 = -14/16

So, -14/16 + 5/16

= -9/16

3. Now, 37/45 - ( -9/16)

37/45 + 9/16 ( since, -- * -- is + )

(LCM = 720)

592/720 + 405/720

= 997/720
