What is x when 88 divided by x equals 100?

To find the answer, just divide the dividend by the quotient: 88 ÷ 100 = 0.88

To prove this, let's compute 88 divided by 0.88: $\frac{88}{0.88} = 100$

How does it work?

Asking what the value of x could be when 88 divided by x gives a result of 100, is equivalent to solving the following equation:

$\frac{88}{x} = 100$

Multiply both sides by x: $\frac{88 x}{x} = 100 x$
$\frac{88 x}{x}$ is equivalent to $\frac{x}{x} \times 88$ , which simplifies to $1 \times 88$ (or just $88$ ).
Thus, the equation becomes: $88 = 100 x$
To find x, divide both sides by 100: $\frac{88}{100} = \frac{100 x}{100}$
Which gives, after simplification: $0.88 = x$ (or $x = 0.88$ )

So, if the dividend is 88 and the quotient is 100, the divisor is 0.88.
