Question

Simplify.....

3/4 + 6/7 - 7/8​

Answer 1

➤ Answer :-

$\longrightarrow \sf \: \frac{3}{4} + \frac{6}{7} - \frac{7}{8}$

First,we should add the fractions.....

$\longrightarrow \sf \: \frac{3}{4} + \frac{6}{7}$

LCM of 4 and 7 is 28.

$\longrightarrow \sf \: \frac{3 \times 7}{4 \times 7} + \frac{6 \times 4}{7 \times 4}$

$\longrightarrow \sf \: \frac{21}{28} + \frac{24}{28} = \frac{21 + 24}{28}$

$\longrightarrow \sf \: \frac{45}{28}$

Now we should subtract $\sf\frac{45}{28}$ and $\sf\frac{7}{8}$

$\longrightarrow \sf \: \frac{45}{28} - \frac{7}{8}$

LCM of 28 and 8 is 224.

$\longrightarrow \sf \: \frac{48 \times 8}{28 \times 8} - \frac{7 \times 28}{8 \times 28}$

$\longrightarrow \sf \: \frac{384}{224} - \frac{196}{224} = \frac{384 - 196}{224}$

$\longrightarrow \sf \: \frac{188}{224}$

$\Huge\therefore$The answer is $\sf\frac{188}{224}$
