Question

Как сделать (5/24+1/24)+(11/60+13/60)

Answer 1

$( \frac{5}{24} + \frac{1}{24} ) + ( \frac{11}{60} + \frac{13}{60})$
$\frac{6}{24} + \frac{24}{60} = \frac{30}{60}$
1/2,там сокращаем и получаем 1/2

Answer 2

$\frac{6}{24} + \frac{24}{60} = \frac{132}{120} = \frac{11}{10} = 1 \times \frac{1}{10}$
