(1/2+1/3+1/6)*24:5-9/22:15/121решите

$( \frac{1}{2} + \frac{1}{3}+ \frac{1}{6})*24:5-\frac{9}{22}: \frac{15}{121}=1,5$

1) $\frac{1}{2}+ \frac{1}{3}= \frac{3*1+2*1}{6}= \frac{3+2}{6}= \frac{5}{6}$

2) $\frac{5}{6}+ \frac{1}{6}= \frac{5+1}{6}= \frac{6}{6}=1$

3) $1*24 = 24$

4) $24:5=4,8$

5) $\frac{9}{22} : \frac{15}{121}= \frac{9}{22}* \frac{121}{15}= \frac{3}{2}* \frac{11}{5}= \frac{33}{10}=3,3$

6) $4,8 - 3,3 = 1,5$
