Answer:
first add the number
-2/7 + 13/4 = (-8+ 91)/28 = 83/28
11/14 + 15/42 = (33+15)/42 = 48/42
= or (48÷6)/(42÷6)
= 8 / 7 (6 As HCF)
in question given subtract the sum of -2/7
and 13/4 = (83/28) from the sum of 11/14 and
15/42 = (8/7)
8/7 - 83/28
LCM of 7 and 28 is 28
=[(4×8)-(1×83)] /28
= [32-83] /28
= -51 /28
