What is x when 35 divided by x equals 80?

To find the answer, just divide the dividend by the quotient: 35 ÷ 80 = 0.4375

To prove this, let's compute 35 divided by 0.4375: $\frac{35}{0.4375} = 80$

How does it work?

Asking what the value of x could be when 35 divided by x gives a result of 80, is equivalent to solving the following equation:

$\frac{35}{x} = 80$

Multiply both sides by x: $\frac{35 x}{x} = 80 x$
$\frac{35 x}{x}$ is equivalent to $\frac{x}{x} \times 35$ , which simplifies to $1 \times 35$ (or just $35$ ).
Thus, the equation becomes: $35 = 80 x$
To find x, divide both sides by 80: $\frac{35}{80} = \frac{80 x}{80}$
Which gives, after simplification: $0.4375 = x$ (or $x = 0.4375$ )

So, if the dividend is 35 and the quotient is 80, the divisor is 0.4375.
