$56.4 + 15 + 3.6 = 60 + 15 = 75 \\ 12.345 + 8.66 - 5.66 = 12.345 + 3 = 15.345 \\ 15.805 - 5.6 - 3.805 = 12 - 5.6 = 6.4$

2

$0.7 \times 0.5 = 0.35 \\ 6.5 \times 5.2 = 33.8 \\ 0.91 \times 0.2 = 0.182$

3

$4.8 \div 0.4 = 12 \\ 6.6 \div 0.6 = 110 \\ 3.5 \div 0.007 = 500$

4

$(8.25 \times 0.1 - 0.025)(2.21 + 4.79) \div 0.1 = (0.825 - 0.025) \frac{7}{0.1} = 0.8 \times 0.7 = 0.56$

5

$8.7 \times 10 = 87 \\ 9.525 \times 100 = 952.5 \\ 9.4 \div 10 = 0.94 \\ 45.5 \div 100 = 0.455$

6

$65.4 \times 0.001 = 0.0654 \\ 323.53 \times 0.01 = 3.2353 \\ 2.718 \div 0.0001 = 27180 \\ 5.03 \div 0.1 = 50.3$

7

$1.6 \times 0.5 + 3.2 = 0.8 + 3.2 = 4 \\ (14 - 2.3)(0.6 + 0.7) = 11.7 \times 1.3 = 15.21$

8

$4.2(x - 2.5) = 6.3 \\ 4.2x - 10.5 = 6.3 \\ 4.2x = 16.8 \\ x = 4$

9

${0.01}^{2} = 0.0001 \\ {0.2}^{2} = 0.04 \\ {0.2}^{3} = 0.08$

10

$\frac{3}{5} = 0.6 \\ \frac{3}{25} = 0.12 \\ 13 \frac{1}{20} = 13.05$
