Answer:
Step-by-step explanation:
=> 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:
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
