Answer 1

1) 10.5/15+1.8= 0,7+1,8=2,5

2) 67.2/12-3.25= 5,6-3,25=2,35

3) 46.2/132*1.6= 0,35*1,6=0,56

4) (16.3+21.5)/14=37,8/14=2,7

5) (42.3+34.2)/9+3.5= 76,5/9+3,5=8,5+3,5=12

6) (47.52-7.2)/6-0.81=40,32/6-0,81=6,72-0,81=5,91

Answer 2

Конечно, я помогу выполнить указанные действия:

1. $\frac{10.5}{15} + 1.8$ $\frac{10.5}{15} + 1.8 = 0.7 + 1.8 = 2.5$

2. $\frac{67.2}{12} - 3.25$ $\frac{67.2}{12} - 3.25 = 5.6 - 3.25 = 2.35$

3. $\frac{46.2}{132} \times 1.6$ $\frac{46.2}{132} \times 1.6 \approx 0.563636 \times 1.6 \approx 0.901818$

4. $\frac{16.3 + 21.5}{14}$ $\frac{16.3 + 21.5}{14} = \frac{37.8}{14} \approx 2.7$

5. $\frac{42.3 + 34.2}{9} + 3.5$ $\frac{42.3 + 34.2}{9} + 3.5 = \frac{76.5}{9} + 3.5 \approx 8.5 + 3.5 = 12$

6. $\frac{47.52 - 7.2}{6} - 0.81$ $\frac{47.52 - 7.2}{6} - 0.81 \approx \frac{40.32}{6} - 0.81 \approx 6.72 - 0.81 \approx 5.91$
