Question

|5,75|+|-2 1/4|
|0|×|-38|
8904: (22×308-6692)
124,5×1,3-(0,321+0,135):1,52
(3/14-2/7+1/2)×14

Answer 1

$1)5.75 + | - 2 \times \frac{1}{4} | \\ 5.75 + 2 \times \frac{1}{4} = \frac{23}{4} + \frac{9}{4} \\ = 8$
$2) = 0$
$3)8904 \div (6776 - 6692) \\ = 8904 \div 84 = 106$
$4)161.85 - 0.456 \div 1.52 = \\ = 161.85 - 0.3 = 161.55$
$5) \frac{3}{7} \times 14 = 3 \times 2 = 6$
