Question

4/5+(7/8+3/4)=(4/5+7/8)+3/4

Answer 1

Answer:

LHS is not equal to RHS

Step-by-step explanation:

4/5+(7/8+3/4)=(4/5+7/8)+3/4

4/5(28+24/8)=(32+35/40)+3/4

4/5+(52/8)=(67/40)+3/4

32+260/40=268+120/40

292/40 = 388/40

Therefore, the LHS not equal to RHS

Answer 2

$\frac{4}{5} + \frac{7}{8} + \frac{3}{4} = \frac{4}{5} + \frac{7}{8} + \frac{3}{4} \\ \frac{4}{5} + \frac{7 + 6}{8} = \frac{32 + 35}{40} + \frac{3}{4} \\ \frac{4}{5} + \frac{13}{8} = \frac{67}{40} + \frac{3}{4} \\ \frac{32 + 65}{40} = \frac{67 + 30}{40} \\ \frac{97}{40} = \frac{97}{40}$
