Question

(7/8-17/12):5/12......

Answer 1

($\frac{7}{8} - \frac{17}{12}$):$\frac{5}{12}$ = - 1,3
1) $\frac{7}{8} - \frac{17}{12}$ = $\frac{7*3}{8*3} - \frac{17*2}{12*2} = \frac{21}{24} - \frac{34}{24} = \frac{21-34}{24} = - \frac{13}{24}$
2) $(- \frac{13}{24} ) : \frac{5}{12} = - \frac{13*12}{24*5} = - \frac{13*12}{2*12*5} = - \frac{13*1}{2*5}$ = $- \frac{13}{10} = - 1 \frac{3}{10}$ = - 1,3
