Answer 1

Ответ:

$1.32.6 \times 5 \frac{1}{4} + 1 \frac{1}{5 } \times 8.5 = 32.6 \times 5.25 + 1.2 \times 8.5 = 171.15 + 10.2 = 181.35 \\ 2. 1 \frac{3}{4} \times 32.8 - 1.12 \times 3.5 = 1.75 \times 32.8 - 3.92 = 57.4 - 3.92 = 53.48 \\ 3.147 - 13 \frac{3}{5} \times 4.8 + 3 \frac{1}{2} \times 6.8 = 147 - 13.6 \times 4.8 + 2.5 \times 6.8 = 147 - 68.28 + 17 = 98.72 4.0.2 \times (5 \times \frac{1}{4} + 6.1) + 0.01 \times 3 = 0.2 \times (5.25 + 6.1) + 0.03 = 0.2 \times 11.35 + 0.03 = 2.27 + 0.03 = 2.3$
