Question

Помогите пожалуйста!!!
1/2+1/2+1/4+3/4=?
Вычесли 3/4 - 5/16=?

Answer 1

$\frac12+\frac12+\frac14+\frac34=\frac{1+1}2+\frac{1+3}4=\frac22+\frac44=1+1=2\\\\\\\frac34-\frac5{16}=\frac{12}{16}-\frac5{16}=\frac7{16}$

Answer 2

Ответ:

$\frac{1}{2} + \frac{1}{2} + \frac{1}{4} + \frac{3}{4} = \frac{2}{4} + \frac{2}{4} + \frac{1}{4} + \frac{3}{4} = \frac{8}{4} = 2$

$\frac{3}{4} - \frac{5}{16} = \frac{12}{16} - \frac{5}{16} = \frac{7}{16}$
