Question

[(7\-8)+(-5\6)]×3\4=(7\-8)×3\4+(5\-6)×3\4​

Answer 1

Answer:

Step-by-step explanation:

LHS

lcm of 8 &6 is 24

-21/24+-20/24 = -41/24x3/4 = -41/32

RHS

-7/8x3/4=-21/32

-5/6x3/4=-15/24

= -21/32+-15/24

lcm of 32 and 24 is 96

= -63/96+-60/96= -123/96

simplified version of -123/96 is -41/32

∴LHS = RHS

Hence,proved
