What is x when 90 divided by x equals 49?

To find the answer, just divide the dividend by the quotient: 90 ÷ 49 = 1.8367346938776

To prove this, let's compute 90 divided by 1.8367346938776: $\frac{90}{1.8367346938776} = 49$

How does it work?

Asking what the value of x could be when 90 divided by x gives a result of 49, is equivalent to solving the following equation:

$\frac{90}{x} = 49$

Multiply both sides by x: $\frac{90 x}{x} = 49 x$
$\frac{90 x}{x}$ is equivalent to $\frac{x}{x} \times 90$ , which simplifies to $1 \times 90$ (or just $90$ ).
Thus, the equation becomes: $90 = 49 x$
To find x, divide both sides by 49: $\frac{90}{49} = \frac{49 x}{49}$
Which gives, after simplification: $1.8367346938776 = x$ (or $x = 1.8367346938776$ )

So, if the dividend is 90 and the quotient is 49, the divisor is 1.8367346938776.
