What is x when 35 divided by x equals 15?

To find the answer, just divide the dividend by the quotient: 35 ÷ 15 = 2.3333333333333

To prove this, let's compute 35 divided by 2.3333333333333: $\frac{35}{2.3333333333333} = 15$

How does it work?

Asking what the value of x could be when 35 divided by x gives a result of 15, is equivalent to solving the following equation:

$\frac{35}{x} = 15$

Multiply both sides by x: $\frac{35 x}{x} = 15 x$
$\frac{35 x}{x}$ is equivalent to $\frac{x}{x} \times 35$ , which simplifies to $1 \times 35$ (or just $35$ ).
Thus, the equation becomes: $35 = 15 x$
To find x, divide both sides by 15: $\frac{35}{15} = \frac{15 x}{15}$
Which gives, after simplification: $2.3333333333333 = x$ (or $x = 2.3333333333333$ )

So, if the dividend is 35 and the quotient is 15, the divisor is 2.3333333333333.
