Пошаговое объяснение:

$1 \frac{2}{5} \div \frac{7}{10} = \frac{(1 \times 5 + 2) \times 10}{5 \times 7} = \frac{2(2 + 5)}{7} = \frac{2 \times 7}{7} = \frac{14}{7} = 2$

Answer 3

Calculating 1 2/5 : 7/10

To calculate the value of 1 2/5 divided by 7/10, we can use the following steps:

1. Convert the mixed numbers to improper fractions. 2. Invert the second fraction (7/10) to find its reciprocal. 3. Multiply the first fraction (1 2/5) by the reciprocal of the second fraction.

Let's proceed with the calculation:

1. Convert 1 2/5 to an improper fraction: - 1 2/5 = (5*1 + 2)/5 = 7/5

2. Invert the fraction 7/10 to find its reciprocal: - The reciprocal of 7/10 is 10/7.

3. Multiply 7/5 by 10/7: - (7/5) * (10/7) = (7*10)/(5*7) = 70/35 = 2

So, 1 2/5 : 7/10 = 2. This result is obtained by converting the mixed numbers to improper fractions, finding the reciprocal of the second fraction, and then multiplying the fractions together.
