Помогите пожалуйста ( 1/4-(-43/90) -37/13-(-43/90) ) (_________ - ___________ ) = ( 79/3...

Решите задачу:

$( \frac{ \frac{1}{4} -(- \frac{43}{90}) }{ \frac{79}{3}} - \frac{- \frac{37}{13}-(- \frac{43}{90}) }{ \frac{79}{3} } = \\ \\ = \frac{ \frac{1}{4} + \frac{43}{90}- ( -\frac{37}{13} + \frac{43}{90}) }{ \frac{79}{3} } = \frac{ \frac{1}{4}+ \frac{43}{90} + \frac{37}{13} - \frac{43}{90} }{ \frac{79}{3} } = \\ \\ = \frac{ \frac{1}{4} + \frac{37}{13} }{ \frac{79}{3} } = \frac{13+148}{52} : \frac{79}{3} = \frac{161}{52} * \frac{3}{79} = \frac{483}{4108}$
