PRECISO DO CÁLCULO

Answer 1

$\frac{5}{4} + \frac{2}{ 3} + \frac{1}{2} = \\ \\ \frac{5 \times 3 + 2 \times 4}{4 \times 3} + \frac{1}{2} = \\ \\ \frac{15 + 8}{12} + \frac{1}{2} = \\ \\ \frac{23}{12} + \frac{1}{2} = \\ \\ \frac{2 \times 23 + 12 \times 1}{2 \times 12} = \\ \\ \frac{46 + 12}{24} = \\ \\ \frac{58}{24} = \\ \\ \frac{58 \div2 }{24 \div 2} = \\ \\ =\frac{29}{12}$

Espero ter ajudado!
