Question

solve the following given above...​

Answer 1

Answer:

1. answer : 3/28

Step-by-step explanation:

1. 1/2 + 3/4 - 8/7

=> LCM = 28

=> (1/2 × 14/14) + (3/4 × 7/7) - (8/7 × 4/4)

=> 14/28 + 21/28 - 32/28

=> 35/28 - 32/28

=> 3/28

Answer 2

Answer:

A. 13/28

B. 19/30

C. 37/30 or 10 7/30

Step-by-step explanation:

A. 1/2 + 3/4 - 8/7

=> 14/28 + 21/28 - 32/28    (Equating denominators with LCM of 2, 4 and 7 which is 28)

=> (14 + 21 - 32)/28 => 13/28

B. 4/5 - 2/3 + 1/2

=> 24/30 - 20/30 + 15/30    (Equating denominators with LCM of 2, 3 and 5 which is 30)

=> (24 - 20 + 15)/30 => 19/30

C. 6/5 + 3/10 - 4/15

=> 36/30 + 9/30 - 8/30    (Equating denominators with LCM of 5, 10 and 15 which is 30)

=> (36 + 9 - 8)/30 => 37/30 or 10 7/30
