What value divided by 31 equals 21?

In other words, what would the dividend be if the divisor were 31 and the quotient 21?

To find the answer, just multiply the divisor with the quotient: 31 × 21 = 651

To prove this, let's compute 651 divided by 31: 651 31 = 21

How does it work?

Asking which value divided by 31 gives a result of 21 is equivalent to solving the following equation:

x 31 = 21

  1. We need to isolate x, so multiply both sides by 31: 31 x 31 = 31 × 21
  2. 31 x 31 is equivalent to 31 31 x , which simplifies to 1 x (or just x ).
  3. Thus: x = 31 × 21 = 651

So, if the divisor is 31 and the quotient is 21, the dividend is 651.
