What is x when 51 divided by x equals 60?

To find the answer, just divide the dividend by the quotient: 51 ÷ 60 = 0.85

To prove this, let's compute 51 divided by 0.85: $\frac{51}{0.85} = 60$

How does it work?

Asking what the value of x could be when 51 divided by x gives a result of 60, is equivalent to solving the following equation:

$\frac{51}{x} = 60$

Multiply both sides by x: $\frac{51 x}{x} = 60 x$
$\frac{51 x}{x}$ is equivalent to $\frac{x}{x} \times 51$ , which simplifies to $1 \times 51$ (or just $51$ ).
Thus, the equation becomes: $51 = 60 x$
To find x, divide both sides by 60: $\frac{51}{60} = \frac{60 x}{60}$
Which gives, after simplification: $0.85 = x$ (or $x = 0.85$ )

So, if the dividend is 51 and the quotient is 60, the divisor is 0.85.
