Calculate the approximate value of given questions:

$sqrt{223.89+59.87-sqrt{399.98}-8}=?-sqrt[3]{511.98}$

$frac{262.87+?}{6.98}+sqrt[3]{1330.96}=(18.87)^{2}-289.86$

$frac{11999.87}{?}+54.9 \%$ of $1800-389.93=11 frac{1}{9} \%$ of $9899.87$

$sqrt{(524.97-489.87)^{2} div(244.89)^{2}}=?-frac{251.93}{293.87}$

$726.98+(13.98)^{2}-sqrt{528.98}=? \%$ of $4998.98$
