Question

Calculati 2+2/4, 1-3/6,1+6/10 Dau coroana! ​

Answer 1

Explicație pas cu pas:

$2 + \frac{2}{4} = \frac{8 + 2}{4} = \frac{10}{4} = \frac{5}{2} = 2.5$

$1 - \frac{3}{6} = \frac{6 - 3}{6} = \frac{3}{6} = \frac{1}{2} = 0.5$

$1 + \frac{6}{10} = \frac{10 + 6}{10} = \frac{16}{10} = \frac{8}{5} = 1.6$

Answer 2

Răspuns:

Explicație pas cu pas:

2 + 2/4 = ²⁾2 + 1/2 = (4 + 1)/2 = 5/2

1 - 3/6 =  ²⁾1 - 1/2 = (2 - 1)/2 = 1/2

1 + 6/10 = ⁵⁾1 + 3/5 = (5 + 3)/5 = 8/5
