What value divided by 7 equals 51?

To find the answer, just multiply the divisor with the quotient: 7 × 51 = 357

To prove this, let's compute 357 divided by 7: $\frac{357}{7} = 51$

How does it work?

Asking which value divided by 7 gives a result of 51 is equivalent to solving the following equation:

$\frac{x}{7} = 51$

We need to isolate x, so multiply both sides by 7: $\frac{7 x}{7} = 7 \times 51$
$\frac{7 x}{7}$ is equivalent to $\frac{7}{7} x$ , which simplifies to $1 x$ (or just $x$ ).
Thus: $x = 7 \times 51 = 357$

So, if the divisor is 7 and the quotient is 51, the dividend is 357.
