Question

8) (16,4 :2 : 9 + 0,1) : 4

Answer 1

(16,4:2:9 + 0,1):4 = $\frac{91}{360}$

1) 16,4:2 = 8,2

2) 8,2:9 = 8$\frac{2}{10}$:9 = $\frac{82}{10}$:9 = $\frac{82}{10*9}$ = $\frac{82}{90}$

3) $\frac{82}{90}$ + 0,1 = $\frac{82}{90}$ + $\frac{1}{10}$ = $\frac{82}{90}$ + $\frac{9}{90}$ = $\frac{91}{90}$

4) $\frac{91}{90}$:4 = $\frac{91}{90*4}$ = $\frac{91}{360}$
