Answer 2

Ответ:

3,5

Пошаговое объяснение:

1) 4 1/9 * 3,3 = 37/9 * 33/10 = 37/3 * 11/10 = 407/30 = 13 17/30

2) 13 17/30 + 126 13/30 = 139 30/30 = 140

3) 140 * 1,5 = 210

4) 210 : 60 = 3,5

Answer 3

To simplify the expression:

1. First, let's deal with the multiplication and division from left to right:

   • $4 \frac{1}{9} \times 3.3 = 4 \frac{1}{9} \times \frac{33}{10} = \frac{4 \times 33}{9 \times 10} = \frac{132}{90} = \frac{22}{15}$
   • $126 \frac{13}{30} \div 1.5 = 126 \frac{13}{30} \div \frac{3}{2} = 126 \frac{13}{30} \times \frac{2}{3} = \frac{126 \times 2}{30 \times 3} + \frac{13}{30 \times 3} = \frac{252}{90} + \frac{13}{90} = \frac{265}{90}$

2. Now, we have: $\left(\frac{22}{15} + \frac{265}{90}\right) \div 60$

3. Find a common denominator for the fractions: $\frac{22}{15} = \frac{22 \times 6}{15 \times 6} = \frac{132}{90}$

4. Now, the expression becomes: $\left(\frac{132}{90} + \frac{265}{90}\right) \div 60$

5. Combine the fractions: $\frac{132 + 265}{90} \div 60 = \frac{397}{90} \div 60$

6. Divide the numerator by the denominator: $\frac{397}{90} \div 60 = \frac{397}{90} \times \frac{1}{60} = \frac{397}{5400}$

7. Simplify the fraction if possible. Both the numerator and denominator are divisible by 7: $\frac{397}{5400} = \frac{397 \div 7}{5400 \div 7} = \frac{56}{771}$

So, the simplified value of the expression is $\frac{56}{771}$.
