What is x when 51 divided by x equals 88?

To find the answer, just divide the dividend by the quotient: 51 ÷ 88 = 0.57954545454545

To prove this, let's compute 51 divided by 0.57954545454545: $\frac{51}{0.57954545454545} = 88$

How does it work?

Asking what the value of x could be when 51 divided by x gives a result of 88, is equivalent to solving the following equation:

$\frac{51}{x} = 88$

Multiply both sides by x: $\frac{51 x}{x} = 88 x$
$\frac{51 x}{x}$ is equivalent to $\frac{x}{x} \times 51$ , which simplifies to $1 \times 51$ (or just $51$ ).
Thus, the equation becomes: $51 = 88 x$
To find x, divide both sides by 88: $\frac{51}{88} = \frac{88 x}{88}$
Which gives, after simplification: $0.57954545454545 = x$ (or $x = 0.57954545454545$ )

So, if the dividend is 51 and the quotient is 88, the divisor is 0.57954545454545.
