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

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