What is x when 70 divided by x equals 84?

To find the answer, just divide the dividend by the quotient: 70 ÷ 84 = 0.83333333333333

To prove this, let's compute 70 divided by 0.83333333333333: $\frac{70}{0.83333333333333} = 84$

How does it work?

Asking what the value of x could be when 70 divided by x gives a result of 84, is equivalent to solving the following equation:

$\frac{70}{x} = 84$

Multiply both sides by x: $\frac{70 x}{x} = 84 x$
$\frac{70 x}{x}$ is equivalent to $\frac{x}{x} \times 70$ , which simplifies to $1 \times 70$ (or just $70$ ).
Thus, the equation becomes: $70 = 84 x$
To find x, divide both sides by 84: $\frac{70}{84} = \frac{84 x}{84}$
Which gives, after simplification: $0.83333333333333 = x$ (or $x = 0.83333333333333$ )

So, if the dividend is 70 and the quotient is 84, the divisor is 0.83333333333333.
