Question

Выполните действия: 1 1/3-3/4*(5/12-/13)

Answer 1

1 целая 1/3 - 3/4 * (5/12 - 1/3)

4/3 - 3/4 * (5/12 - 4/12) = 4/3 - 3/4 * 1/12 = 4/3 - 3/48 = 64/48 - 3/48 =
61/48 = 1 целая 13/48

Answer 2

$1 \frac{1}{3} - \frac{3}{4} *( \frac{5}{12} - \frac{1}{3} )= 1 \frac{1}{3} - \frac{3}{4} * \frac{5}{12} +\frac{3}{4} * \frac{1}{3} =1 \frac{1}{3} - \frac{1}{4} * \frac{5}{4} +\frac{1}{4} * \frac{1}{1} =$$1 \frac{16}{48} - \frac{15}{48} +\frac{12}{48} =1\frac{1}{48} +\frac{12}{48}=1\frac{13}{48}$
