Step-by-step explanation:

(9x7/4x7 + 23x2/14x2) - ( -4x2/7x2 + 5/14)

(63+46/28) - (-3/14)

109/28 + 6/28 = 112/28

112/28 = 4

Answer 2

➤ Answer :-

$\dashrightarrow \tt \bigg(\frac{9}{4} + \frac{23}{14} \bigg) - \bigg( \frac{( - 4)}{7} + \frac{5}{14} \bigg)$

LCM of 4 and 14 is 28.

LCM of 7 and 14 is 14.

$\dashrightarrow \tt\frac{9 \times 6}{4 \times 6} + \frac{23 \times 2}{14 \times 2} - \frac{( - 4) \times 2}{7 \times 2} + \frac{5}{14}$

$\dashrightarrow \tt \bigg( \frac{54}{28} + \frac{46}{28} \bigg) - \bigg( \frac{( - 8)}{14} + \frac{5}{14} \bigg)$

$\dashrightarrow \sf \bigg(\frac{54 + 46}{28} \bigg) - \bigg( \frac{( - 8) + 5}{14} \bigg)$

$\dashrightarrow \tt \frac{100}{28} - \frac{( - 40)}{14}$

LCM of 28 and 14 is 28.

$\dashrightarrow \tt \frac{100}{28} - \frac{( - 40) \times 2}{14 \times 2}$

$\dashrightarrow \tt\frac{100}{28} - \frac{( - 80)}{28} = \frac{100 - ( - 80)}{28}$

$\dashrightarrow \tt \frac{180}{28} = 6 \frac{12}{28}$

$\Huge\therefore$The answer is $\tt 6 \frac{12}{28}$
