Question

4n/5+n/4-n/2=11/10 check the answer with process​

Answer 1

Answer:

$→\frac{4n}{5} + \frac{n}{4} -\frac{n}{2} = \frac{11}{10} \\ \frac{(16n + 5n - 10n)}{20} = \frac{11}{10} \\ \frac{11n}{20} = \frac{11}{10} \\ n = \frac{11}{10} \times \frac{20}{11} \\ \boxed{n = 2}✓$

• n = 2 is the right answer.

Checking procedure :

• Left Hand Side

$→\frac{4(2)}{5} + \frac{(2)}{4} - \frac{(2)}{2} \\ = \frac{8}{5} + \frac{1}{2} - 1 \\ = \frac{16 + 5 - 10}{10} \\ = \boxed{\frac{11}{10} }$

• Right Hand Side

$→ \boxed{ \frac{11}{10} }$

Therefore, LHS = RHS ( Hence proved)
