simplify (1-s/t)/(1+s/t)

simplify

\frac{1 - \frac{s}{t}}{1 + \frac{s}{t}}

\frac{t - s}{t + s}

Solution steps

\frac{1 - \frac{s}{t}}{1 + \frac{s}{t}}

Join

1 - \frac{s}{t} : \frac{t - s}{t}

= \frac{\frac{t - s}{t}}{1 + \frac{s}{t}}

Join

1 + \frac{s}{t} : \frac{t + s}{t}

= \frac{\frac{t - s}{t}}{\frac{t + s}{t}}

Apply the fraction rule:

\frac{\frac{a}{b}}{\frac{c}{d}} = \frac{a \cdot d}{b \cdot c}

= \frac{( t - s ) t}{t ( t + s )}

Cancel the common factor:

t

= \frac{t - s}{t + s}

\frac{1}{3} (6 - 3 x) + \frac{1}{4} (x - 1) (x - 2) = \frac{x ^{2}}{4}

2 t^{2} + 13 t + 6

3 x^{2} - 5 x + 3 > 2 x^{2} + x - 4

x^{\frac{1}{4}} \cdot x^{\frac{1}{2}}

r - 2 = 5
