In a division sum,the quotient is $120$,the divisor is $456$,and the remainder is $333$. Find the dividend.

If doubling a number and adding $20$ to the result gives the same answer as multiplying the number by $8$ and taking away $4$ from the product,the number is

$499.99 + 1999 \div 39.99 \times 50.01 = ?$

The square root of $\left[\frac{(3.25)^{3}}{3.25-1}-\left(3.25+(3.25)^{2}+1\right)\right]$ is equal to

$3149 \times 1?5 = 425115$

$\frac{6}{5}$ of $\frac{3}{4}$ of $\frac{1}{2}$ of $? = 3600$
