Answer 2

Let's break down the given expression step by step:

1. $1,8:2$ - Divide 1.8 by 2, which equals $0.9$.
2. $\frac{1}{4}$ - This is $0.25$ as a decimal.
3. $1,8 \times \frac{1}{3}$ - Multiply 1.8 by $\frac{1}{3}$, which equals $0.6$.
4. Subtract the result from step 3 ($0.6$) from the result of step 1 ($0.9$): $0.9 - 0.6 = 0.3$.
5. Multiply the result from step 4 ($0.3$) by 57: $0.3 \times 57 = 17.1$.
6. Finally, add 17.1 to $4.3$: $17.1 + 4.3 = 21.4$.

So, the value of the given expression is $21.4$.
