What is x when 37 divided by x equals 21?

To find the answer, just divide the dividend by the quotient: 37 ÷ 21 = 1.7619047619048

To prove this, let's compute 37 divided by 1.7619047619048: $\frac{37}{1.7619047619048} = 21$

How does it work?

Asking what the value of x could be when 37 divided by x gives a result of 21, is equivalent to solving the following equation:

$\frac{37}{x} = 21$

Multiply both sides by x: $\frac{37 x}{x} = 21 x$
$\frac{37 x}{x}$ is equivalent to $\frac{x}{x} \times 37$ , which simplifies to $1 \times 37$ (or just $37$ ).
Thus, the equation becomes: $37 = 21 x$
To find x, divide both sides by 21: $\frac{37}{21} = \frac{21 x}{21}$
Which gives, after simplification: $1.7619047619048 = x$ (or $x = 1.7619047619048$ )

So, if the dividend is 37 and the quotient is 21, the divisor is 1.7619047619048.
