Question

simplify the expression 1-3/7-9/2+3/4-(1/2-3/4)​

Answer 1

Answer:

$\boxed{- \frac{41}{14} }$

Step-by-step explanation:

$Simplify \: the \: following: \\ = > 1 - \frac{3}{7} - \frac{9}{2} + \frac{3}{4} - ( \frac{1}{2} - \frac{3}{4} ) \\ \\ Put \: \frac{1}{2} - \frac{3}{4} \: over \: the \: common \: denominator \: 4 : \\ \frac{1}{2} - \frac{3}{4} = \frac{2}{4} - \frac{3}{4} : \\ = > 1 - \frac{3}{7} - \frac{9}{2} + \frac{3}{4} - \boxed{\frac{2}{4} - \frac{3}{4}} \\ \\ \frac{2}{4} - \frac{3}{4} = \frac{2 - 3}{4} : \\ = > 1 - \frac{3}{7} - \frac{9}{2} + \frac{3}{4} - \boxed{ \frac{2 - 3}{4}} \\ \\ 2 - 3 = - 1 : \\ = > 1 - \frac{3}{7} - \frac{9}{2} + \frac{3}{4} - \frac{ \boxed{ - 1}}{4} \\ \\ - ( - 1) = 1 : \\ = > 1 - \frac{3}{7} - \frac{9}{2} + \frac{3}{4} + \boxed{ \frac{1}{4} } \\ \\ Put \: 1 - \frac{3}{7} - \frac{9}{2} + \frac{3}{4} + \frac{1}{4} \: over \: the \: common \\ denominator \: 28 : \\ 1 - \frac{3}{7} - \frac{9}{2} + \frac{3}{4} + \frac{1}{4} = \frac{28}{28} + \frac{4( - 3)}{28} + \frac{14( - 9)}{28} + \frac{7 \times 3}{28} + \frac{7}{28} : \\ = > \frac{28}{28} + \frac{4( - 3)}{28} + \frac{14( - 9)}{28} + \frac{7 \times 3}{28} + \frac{7}{28}$

$\\ 4( - 3) = - 12 : \\ = > \frac{28}{28} + \frac{ \boxed{ - 12}}{28} + \frac{14( - 9)}{28} + \frac{7 \times 3}{28} + \frac{7}{28} \\ \\ 14( - 9) = - 126 : \\ = > \frac{28}{28} - \frac{12}{28} + \frac{ \boxed{ - 126}}{28} + \frac{7 \times 3}{28} + \frac{7}{28} \\ \\ 7 \times 3 = 21 : \\ = > \frac{28}{28} - \frac{12}{28} - \frac{126}{28} + \frac{ \boxed{21}}{28} + \frac{7}{28} \\ \\ \frac{28}{28} - \frac{12}{28} - \frac{126}{28} + \frac{21}{28} + \frac{7}{28} = \frac{28 - 12 - 126 + 21 + 7}{28} : \\ = > \frac{28 - 12 - 126 + 21 + 7}{28} \\ \\ 28 - 12 - 126 + 21 + 7 = (28 + 21 + 7) - (12 + 126) : \\ = > \frac{ \boxed{(28 + 21 + 7) - (12 + 126)}}{28} \\ \\ 28 + 21 + 7 = 56 : \\ = > \frac{ \boxed{56} - (12 + 126)}{28} \\ \\ 12 + 126 = 138 : \\ = > \frac{56 - \boxed{138}}{28} \\ \\ 56 - 138 = - (138 - 56) : \\ = > \frac{ \boxed{- (138 - 56)}}{28} \\ \\ 138 - 56 = 82 : \\ = > \frac{ - \boxed{82}}{28} \\ \\ = > \frac{ - (2 \times 41)}{2 \times 14} \\ \\ = > \frac{ \cancel{2}} { \cancel{2}} \times ( - \frac{41}{14} ) \\ \\ \\ = > - \frac{41}{14}$
