(9-2 2/3 • 2 1/7) • 21/46
Помогите пожалуйста!

Answer 1

1) 2 2/3* 2 1/7= 8/3*15/7= 40/7= 5 5/7
2) 9-5 5/7= 4- 5/7= 4/1-5/7=28/7-5/7= 23/7
3)23/7*21/46= 3/2

Answer 2

(9 - $\frac{2}{3}$ * 2$\frac{1}{7}$ ) * $\frac{21}{46}$ = 1$\frac{1}{2}$

1) 2$\frac{2}{3}$ * 2$\frac{1}{7}$ = $\frac{8}{3}$ * $\frac{15}{7}$ = $\frac{40}{7}$ = 5$\frac{5}{7}$

2) 9 - 5$\frac{5}{7}$ = 8$\frac{7}{7}$ - 5$\frac{5}{7}$ = 3$\frac{2}{7}$

3) 3$\frac{2}{7}$ *$\frac{21}{46}$ = $\frac{23}{7}$ * $\frac{21}{46}$ = $\frac{3}{2}$ = 1$\frac{1}{2}$
