What is x when 70 divided by x equals 7?

To find the answer, just divide the dividend by the quotient: 70 ÷ 7 = 10

To prove this, let's compute 70 divided by 10: $\frac{70}{10} = 7$

How does it work?

Asking what the value of x could be when 70 divided by x gives a result of 7, is equivalent to solving the following equation:

$\frac{70}{x} = 7$

Multiply both sides by x: $\frac{70 x}{x} = 7 x$
$\frac{70 x}{x}$ is equivalent to $\frac{x}{x} \times 70$ , which simplifies to $1 \times 70$ (or just $70$ ).
Thus, the equation becomes: $70 = 7 x$
To find x, divide both sides by 7: $\frac{70}{7} = \frac{7 x}{7}$
Which gives, after simplification: $10 = x$ (or $x = 10$ )

So, if the dividend is 70 and the quotient is 7, the divisor is 10.
