Answer 2

Respuesta:

$3( \frac{1}{4} + \frac{1}{2} ) - 2 \times {( \frac{1}{4} })^{2} = 3( \frac{4 \div 4 \times 1 + 4 \div 2 \times 1}{4} ) - 2 \times \frac{ {1}^{2} }{ {4}^{2} } = 3( \frac{1 + 2}{4} ) - 2 \times \frac{1}{16} = 3 \times ( \frac{3}{4} ) - \frac{2 \times 1}{16} = \frac{3 \times 3}{4} - \frac{2}{16} = \frac{9}{4} - \frac{2}{16} = \frac{16 \div 4 \times 9 - 16 \div 16 \times 2}{16} = \frac{36 - 2}{16 } = \frac{34}{16}$

simplifico

$\frac{34 \div 2}{16 \div 2} = \frac{17}{8}$

resultado 17/8
