Answer 1

Пошаговое объяснение:

5 7/3 : 7 8/1 =5 7/3 : 15=22/3 : 15 = 22/45

4 15/8 : 1 25/9=47/8 : 34/9 = 47 * 9/8*34 =423/272 = 1 151/272

1 15/13 : 1 5/3=28/13 : 8/3= 28 * 3/13 * 8=84/104=21 * 4/26 * 4=21/ 26

Answer 2

To solve these division problems involving mixed numbers, you can follow these steps:

1. Convert the mixed numbers into improper fractions.
2. Invert the second fraction (the divisor).
3. Multiply the first fraction (the dividend) by the inverted second fraction.

Let's apply these steps to each of your problems:

4. $525 \frac{7}{3} \div 7 \frac{8}{1}$:

   First, convert the mixed numbers to improper fractions:

   • $525 \frac{7}{3} = \frac{1578}{3}$
   • $7 \frac{8}{1} = \frac{56}{1}$

   Invert the second fraction (the divisor):

   • Inverting $\frac{56}{1}$ gives $\frac{1}{56}$.

   Now, multiply the first fraction by the inverted second fraction: $\frac{1578}{3} \div \frac{1}{56} = \frac{1578}{3} \cdot \frac{56}{1} = \frac{88488}{3}$

   To simplify, divide both the numerator and denominator by their greatest common factor (3): $\frac{88488}{3} ÷ 3 = \frac{29496}{1} = 29496$

So, $525 \frac{7}{3} \div 7 \frac{8}{1} = 29496$.

5. $4 \frac{15}{8} \div 1 \frac{25}{9}$:

   First, convert the mixed numbers to improper fractions:

   • $4 \frac{15}{8} = \frac{47}{8}$
   • $1 \frac{25}{9} = \frac{34}{9}$

   Invert the second fraction (the divisor):

   • Inverting $\frac{34}{9}$ gives $\frac{9}{34}$.

   Now, multiply the first fraction by the inverted second fraction: $\frac{47}{8} \div \frac{9}{34} = \frac{47}{8} \cdot \frac{34}{9} = \frac{1598}{72}$

   To simplify, divide both the numerator and denominator by their greatest common factor (2): $\frac{1598}{72} ÷ 2 = \frac{799}{36} = \frac{199}{9}$

So, $4 \frac{15}{8} \div 1 \frac{25}{9} = \frac{199}{9}$.

6. $1 \frac{15}{13} \div 1 \frac{5}{3}$:

   First, convert the mixed numbers to improper fractions:

   • $1 \frac{15}{13} = \frac{28}{13}$
   • $1 \frac{5}{3} = \frac{8}{3}$

   Invert the second fraction (the divisor):

   • Inverting $\frac{8}{3}$ gives $\frac{3}{8}$.

   Now, multiply the first fraction by the inverted second fraction: $\frac{28}{13} \div \frac{3}{8} = \frac{28}{13} \cdot \frac{8}{3} = \frac{224}{39}$
