Question

Вычилисте пожалуйста. 5/6 * 1/2 2/3 * 2/5 4/3 * 5/7 3/10 * 3/10 3/4 * 3/7 5/7 * 9/1 Помогите Прошу

Answer 1

$\frac{5}{6} * \frac{1}{2} = \frac{5}{12}$
$\frac{2}{3} * \frac{2}{5} = \frac{4}{15}$
$\frac{4}{3} * \frac{5}{7} = \frac{20}{21}$
$\frac{3}{10} + \frac{3}{10} = \frac{9}{100}$
$\frac{3}{4} + \frac{3}{7} = \frac{9}{28}$
$\frac{5}{7} + \frac{9}{1} = \frac{45}{7} =6 \frac{3}{7}$

Answer 2

5/6*1/2=5*1/6*2=5/12.
2/3*2/5=2*2/3*5=4/15.
4/3*5/7=4*5/3*7=20/21.
3/10*3/10=3*3/10*10=9/100.
3/4*3/7=3*3/4*7=9/28.
5/7*9/1=5*9/7*1=45/7=6 3/7.
