Question

0,2*7 --------- = 0,42 0,04*0,025 ------------------- = 0,9-0,88

Answer 1

Пошаговое объяснение:

$\frac{0.2 \times 7}{0.42} = \frac{1 \times 7}{2.1} = \frac{1}{0.3} = 1 \frac{10}{3} = 3 \frac{1}{3} \\ \frac{0.04 \times 0.025}{0.9 - 0.88} = \frac{0.04 \times 0.025}{0.02} = \frac{2 \times 0.025}{1} = 0.05$

Answer 2

To solve the equations, let's perform the calculations step by step:

1. 0.2 * 7: Multiply 0.2 by 7: 0.2 * 7 = 1.4 Therefore, 0.2 * 7 = 1.4

2. 0.04 * 0.025: Multiply 0.04 by 0.025: 0.04 * 0.025 = 0.001 Therefore, 0.04 * 0.025 = 0.001

3. 0.9 - 0.88: Subtract 0.88 from 0.9: 0.9 - 0.88 = 0.02 Therefore, 0.9 - 0.88 = 0.02

So, the results are:

• 0.2 * 7 = 1.4
• 0.04 * 0.025 = 0.001
• 0.9 - 0.88 = 0.02
