Question

вычислите 5/2*5/8+7/4*1/4

Answer 1

5/2*5/8+7/4*1/4=25/16+7/16=32/16=2

Answer 2

$\frac{5}{2} * \frac{5}{8} + \frac{7}{4} * \frac{1}{4} = 2$ 
$1. \frac{5}{2} * \frac{5}{8} = \frac{25}{16}$
$2. \frac{7}{4} * \frac{1}{4} = \frac{7}{16}$
$3. \frac{25}{16} + \frac{7}{16} = \frac{32}{16} = 2$
