2)12,3×0,457=5,6211
3)56,211/5,6211=10

Answer 2

To evaluate the expression 1,23 * 45,7 / 12,3 * 0,457, we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

However, it seems like you're using commas (,) instead of decimal points (.) in your numbers. In many numerical systems, including English, decimal points are used to separate the whole number from the fractional part. So, to correctly evaluate the expression, we need to replace the commas with decimal points.

Assuming the expression is: 1.23 * 45.7 / 12.3 * 0.457

Now let's solve it step by step:

1.23 * 45.7 = 56.211 56.211 / 12.3 = 4.573902 4.573902 * 0.457 = 2.090429514

Therefore, the result of the expression 1.23 * 45.7 / 12.3 * 0.457 is approximately 2.090429514.
