Question

O quadrado de 2/5 mais o triplo de 1/2
$\frac{2}{5} \frac{1}{2}$

Answer 1

$(\frac{2}{5})^{2} + 3 * \frac{1}{2} =$


$\frac{2^{2}}{5^{2}} + 3 * \frac{1}{2} =$


$\frac{4}{25} + \frac{3}{2} =$



25 * 2 = 50...



$\frac{4}{25} + \frac{3}{2} = \frac{(2 * 4) + (3 * 25)}{50} =$


$\frac{(8) + (75)}{50} =$


$\frac{83}{50}$
