Answer 1

Запишем смешанную дробь в виде неправильной дроби:
Объяснение: $1\frac{1}{2} = \frac{1*2+1}{2} = \frac{3}{2}$

$1\frac{1}{3} = \frac{4}{3}$
$1\frac{1}{4} = \frac{5}{4}$
$1\frac{2}{3} = \frac{5}{3}$
$1\frac{3}{4} = \frac{7}{4}$
$2\frac{1}{4} = \frac{9}{4}$
$3\frac{1}{5} = \frac{16}{5}$
$8\frac{1}{3} = \frac{25}{3}$
$2\frac{2}{5} = \frac{12}{5}$
$9\frac{5}{7} = \frac{68}{7}$
$1\frac{5}{11} = \frac{16}{11}$
$1\frac{4}{13} = \frac{17}{13}$
$6\frac{1}{12} = \frac{73}{12}$
$4\frac{4}{15} = \frac{64}{15}$
$12\frac{2}{3} = \frac{38}{3}$

Converting Mixed Fractions to Improper Fractions

To convert mixed fractions to improper fractions, we need to multiply the whole number by the denominator of the fraction and add the numerator. The result becomes the new numerator, while the denominator remains the same.

Let's convert the given mixed fractions to improper fractions:

1 1/2 = (1 * 2 + 1) / 2 = 3/21 1/3 = (1 * 3 + 1) / 3 = 4/31 1/4 = (1 * 4 + 1) / 4 = 5/41 2/3 = (1 * 3 + 2) / 3 = 5/31 3/4 = (1 * 4 + 3) / 4 = 7/42 1/4 = (2 * 4 + 1) / 4 = 9/43 1/5 = (3 * 5 + 1) / 5 = 16/58 1/3 = (8 * 3 + 1) / 3 = 25/32 2/5 = (2 * 5 + 2) / 5 = 12/59 5/7 = (9 * 7 + 5) / 7 = 68/71 5/11 = (1 * 11 + 5) / 11 = 16/111 4/13 = (1 * 13 + 4) / 13 = 17/136 1/12 = (6 * 12 + 1) / 12 = 73/124 4/15 = (4 * 15 + 4) / 15 = 64/1512 2/3 = (12 * 3 + 2) / 3 = 38/3

Summary:

The mixed fractions have been converted to improper fractions as follows:

1 1/2 = 3/2 1 1/3 = 4/3 1 1/4 = 5/4 1 2/3 = 5/3 1 3/4 = 7/4 2 1/4 = 9/4 3 1/5 = 16/5 8 1/3 = 25/3 2 2/5 = 12/5 9 5/7 = 68/7 1 5/11 = 16/11 1 4/13 = 17/13 6 1/12 = 73/12 4 4/15 = 64/15 12 2/3 = 38/3
