Question

$frac{3}{14} * (1 frac{1}{2}*14:28)+48 frac{3}{5} :6 frac{3}{4}* frac{5}{12}$

Answer 1

По действиям:
1)1$frac{1}{2}$*14 = $frac{3*14}{2}$ = 21
2)21:28 = $frac{21}{28}$
3)$frac{3}{14}$*$frac{21}{28}$ = $frac{9}{56}$
4)48$frac{3}{5}$:6$frac{3}{4}$ = $frac{243*4}{5*27}$ = $frac{36}{5}$
5)$frac{36}{5}$*$frac{5}{12}$ = $frac{36*5}{5*12}$ = 3
6)$frac{9}{56}$+3 = $frac{9}{56}$+$frac{168}{56}$ = $frac{177}{56}$ = 3$frac{9}{56}$
