What is x when 90 divided by x equals 98?

To find the answer, just divide the dividend by the quotient: 90 ÷ 98 = 0.91836734693878

To prove this, let's compute 90 divided by 0.91836734693878: $\frac{90}{0.91836734693878} = 98$

How does it work?

Asking what the value of x could be when 90 divided by x gives a result of 98, is equivalent to solving the following equation:

$\frac{90}{x} = 98$

Multiply both sides by x: $\frac{90 x}{x} = 98 x$
$\frac{90 x}{x}$ is equivalent to $\frac{x}{x} \times 90$ , which simplifies to $1 \times 90$ (or just $90$ ).
Thus, the equation becomes: $90 = 98 x$
To find x, divide both sides by 98: $\frac{90}{98} = \frac{98 x}{98}$
Which gives, after simplification: $0.91836734693878 = x$ (or $x = 0.91836734693878$ )

So, if the dividend is 90 and the quotient is 98, the divisor is 0.91836734693878.
