What is x when 31 divided by x equals 88?

To find the answer, just divide the dividend by the quotient: 31 ÷ 88 = 0.35227272727273

To prove this, let's compute 31 divided by 0.35227272727273: $\frac{31}{0.35227272727273} = 88$

How does it work?

Asking what the value of x could be when 31 divided by x gives a result of 88, is equivalent to solving the following equation:

$\frac{31}{x} = 88$

Multiply both sides by x: $\frac{31 x}{x} = 88 x$
$\frac{31 x}{x}$ is equivalent to $\frac{x}{x} \times 31$ , which simplifies to $1 \times 31$ (or just $31$ ).
Thus, the equation becomes: $31 = 88 x$
To find x, divide both sides by 88: $\frac{31}{88} = \frac{88 x}{88}$
Which gives, after simplification: $0.35227272727273 = x$ (or $x = 0.35227272727273$ )

So, if the dividend is 31 and the quotient is 88, the divisor is 0.35227272727273.
