For the following questions answer them individually
$$\frac{15\times11+45}{13\times9-30}=?$$
$$39852 \div \sqrt{?} = 81 \times 12$$
54679 + 34521 = ? + 43668
44% of 766 + ? = 900
67% of (?) = 5287.64
$$\sqrt{17956}=?$$
$$30\% of 200 +\sqrt{?} = 48\% of 550 - 10\% of 150$$
$$11.6 \times 8.9 \times 5.1 = ?$$
$$2637 \div 36 = ?$$
$$11160 \div 45 \div 8 = ?$$
