Answer 1

Відповідь:

1) 2,75 ÷ 0,5 = (2,75 × 10) : (0,5 × 10) = 27,5 : 5=5,5

2) 3,4 : 0,17 = (3,4 × 100) : (0,17 ×100) =340 : 17=20

Answer 2

Let's solve these equations step by step:

1. $\frac{2.75}{0.5} = \frac{2.75 \times 5}{0.5 \times 5}$

First, we multiply both the numerator and the denominator by 5 to eliminate the decimal point in the denominator:

$\frac{2.75 \times 5}{0.5 \times 5} = \frac{13.75}{2.5}$

Now we can perform the division:

$\frac{13.75}{2.5} = 5.5$

So, $\frac{2.75}{0.5} = 5.5$.

2. $\frac{3.4}{0.17} = \frac{3.4 \times 20}{0.17 \times 20}$

Similarly, we multiply both the numerator and the denominator by 20:

$\frac{3.4 \times 20}{0.17 \times 20} = \frac{68}{3.4}$

Now we can perform the division:

$\frac{68}{3.4} = 20$

So, $\frac{3.4}{0.17} = 20$.

In the second part of the equation, you've mentioned two dots (..) which might represent placeholders for some values. If you provide those values, I can help you further with the calculations.
