Question

1) calculati 2 pe 5 plus 1 pe 10 plus 1 pe 2 egal 2)1 pe 4 plus 1 pe 3 egal

Answer 1

1) 2/5 + 1/10 + 1/2 = ( 4 + 1 + 5 )/10 = ( 5 + 5 )/10 = 10/10 = 1

2) 1/4 + 1/3 = ( 3 + 4 )/12 = 7/12

Answer 2

Răspuns:

Explicație pas cu pas:

1)

$\frac{ {2}^{( \cdot2} }{5} + \frac{1}{10} + \frac{ {1}^{( \cdot5} }{2} = \frac{4}{10 } + \frac{1}{10} + \frac{5}{10 } = \frac{4 + 1 + 5}{10} = \frac{10}{10} = 10 \div 10 = \boxed{1}$

2)

$\frac{ {1}^{( \cdot3} }{4} + \frac{ {1}^{( \cdot4} }{3} = \frac{3}{12} + \frac{4}{12} = \boxed{ \frac{7}{12} }$
