Question

10. Verify 5/6 - (2/7 + 3/8) = (5/6 - 2/7) + 3/8​

Answer 1

29/168 is not equal to 155/168

Step-by-step explanation

LHS=5/6-(2/7+3/8)

         = 5/6-(2/7*8+3/8*7)    (multiply both in numerator and denominator)

       =5/6-(16/56+21/56)

       =5/6-37/56

       =5/6*28-37/56*3 (multiply both in numerator and denominator)

        =140/168-111/168

        =29/168

RHS= (5/6-2/7)+3/8

       =(5/6*7-2/7*6)+3/8 (multiply both in numerator and denominator)

       =35/42-12/42+3/8

       =23/42+3/8

       =23/42*4+3/8*21 (multiply both in numerator and denominator)

       =92/168+63/168

       =155/168

29/168 is not equal to 155/168

Answer 2

Answer:

L.H.S

5/6 - (2/7 + 3/8)

=5/6 - 37/56

=29/168

R.H.S

(5/6 - 2/7) + 3/8

=23/42 + 3/8

=155/168

Therefore L.H.S is not equal to R.H.S
