What is x when 65 divided by x equals 87?

To find the answer, just divide the dividend by the quotient: 65 ÷ 87 = 0.74712643678161

To prove this, let's compute 65 divided by 0.74712643678161: $\frac{65}{0.74712643678161} = 87$

How does it work?

Asking what the value of x could be when 65 divided by x gives a result of 87, is equivalent to solving the following equation:

$\frac{65}{x} = 87$

Multiply both sides by x: $\frac{65 x}{x} = 87 x$
$\frac{65 x}{x}$ is equivalent to $\frac{x}{x} \times 65$ , which simplifies to $1 \times 65$ (or just $65$ ).
Thus, the equation becomes: $65 = 87 x$
To find x, divide both sides by 87: $\frac{65}{87} = \frac{87 x}{87}$
Which gives, after simplification: $0.74712643678161 = x$ (or $x = 0.74712643678161$ )

So, if the dividend is 65 and the quotient is 87, the divisor is 0.74712643678161.
