What is x when 87 divided by x equals 49?

To find the answer, just divide the dividend by the quotient: 87 ÷ 49 = 1.7755102040816

To prove this, let's compute 87 divided by 1.7755102040816: $\frac{87}{1.7755102040816} = 49$

How does it work?

Asking what the value of x could be when 87 divided by x gives a result of 49, is equivalent to solving the following equation:

$\frac{87}{x} = 49$

Multiply both sides by x: $\frac{87 x}{x} = 49 x$
$\frac{87 x}{x}$ is equivalent to $\frac{x}{x} \times 87$ , which simplifies to $1 \times 87$ (or just $87$ ).
Thus, the equation becomes: $87 = 49 x$
To find x, divide both sides by 49: $\frac{87}{49} = \frac{49 x}{49}$
Which gives, after simplification: $1.7755102040816 = x$ (or $x = 1.7755102040816$ )

So, if the dividend is 87 and the quotient is 49, the divisor is 1.7755102040816.
