What is x when 48 divided by x equals 19?

To find the answer, just divide the dividend by the quotient: 48 ÷ 19 = 2.5263157894737

To prove this, let's compute 48 divided by 2.5263157894737: $\frac{48}{2.5263157894737} = 19$

How does it work?

Asking what the value of x could be when 48 divided by x gives a result of 19, is equivalent to solving the following equation:

$\frac{48}{x} = 19$

Multiply both sides by x: $\frac{48 x}{x} = 19 x$
$\frac{48 x}{x}$ is equivalent to $\frac{x}{x} \times 48$ , which simplifies to $1 \times 48$ (or just $48$ ).
Thus, the equation becomes: $48 = 19 x$
To find x, divide both sides by 19: $\frac{48}{19} = \frac{19 x}{19}$
Which gives, after simplification: $2.5263157894737 = x$ (or $x = 2.5263157894737$ )

So, if the dividend is 48 and the quotient is 19, the divisor is 2.5263157894737.
