What is x when 14 divided by x equals 10?

To find the answer, just divide the dividend by the quotient: 14 ÷ 10 = 1.4

To prove this, let's compute 14 divided by 1.4: $\frac{14}{1.4} = 10$

How does it work?

Asking what the value of x could be when 14 divided by x gives a result of 10, is equivalent to solving the following equation:

$\frac{14}{x} = 10$

Multiply both sides by x: $\frac{14 x}{x} = 10 x$
$\frac{14 x}{x}$ is equivalent to $\frac{x}{x} \times 14$ , which simplifies to $1 \times 14$ (or just $14$ ).
Thus, the equation becomes: $14 = 10 x$
To find x, divide both sides by 10: $\frac{14}{10} = \frac{10 x}{10}$
Which gives, after simplification: $1.4 = x$ (or $x = 1.4$ )

So, if the dividend is 14 and the quotient is 10, the divisor is 1.4.
