Answer 1

Ответ:

1) 50,3 *  8,5 + 72,52 = 427.55+72.52=500.07

2)  600 – 20 1/3 : 15 1/4 · 29.7=$600-5\frac{1}{3} *\frac{1}{15} *\frac{297}{10} =\\600-\frac{1}{3} *\frac{99}{10} \\600-\frac{33}{10} = \frac{5967}{10} =596.7$

Answer 2

To solve the expression you've provided, let's break it down step by step:

1. 50.3 ✖ 8.5

Multiply 50.3 by 8.5: 50.3 ✖ 8.5 = 427.55

2. 427.55 + 72.52

Add 427.55 and 72.52: 427.55 + 72.52 = 500.07

3. 600 – 20 1/3

First, convert the mixed number to an improper fraction: 20 1/3 = (20 * 3 + 1) / 3 = 61/3

Subtract 61/3 from 600: 600 - 61/3 = 179/3

4. 15 1/4 · 29.7

Convert the mixed number to an improper fraction: 15 1/4 = (15 * 4 + 1) / 4 = 61/4

Multiply 61/4 by 29.7: (61/4) * 29.7 = 1825.175

5. 179/3 ÷ 1825.175

Divide 179/3 by 1825.175: (179/3) ÷ 1825.175 = 0.032487

Finally, let's add the results from step 2 and step 5:

500.07 + 0.032487 = 500.102487

Therefore, the result of the expression is approximately 500.102487.
