Question

reduce esta expresión a una sola fracción:

(1/1 + 1/3) - (3/4 + 1/2) × (1/3 - 1/4)
​

Answer 1

$(\frac{1}{1} +\frac{1}{3} ) - (\frac{3}{4} + \frac{1}{2}) * (\frac{1}{3} - \frac{1}{4})$

$(\frac{3}{3} +\frac{1}{3} ) - (\frac{3}{4} + \frac{2}{4}) * (\frac{4}{12} - \frac{3}{12})$

$(\frac{3+1}{3}) - (\frac{3+2}{4}}) * (\frac{4-3}{12})$

$(\frac{4}{3}) - (\frac{5}{4}}) * (\frac{1}{12})$

$(\frac{4}{3}) - \frac{5*1}{4*12}}$

$\frac{4}{3} - \frac{5}{48}}$

$\frac{64}{48} - \frac{5}{48}}$

$\frac{59}{48}$
