What value divided by 21 equals 7?

In other words, what would the dividend be if the divisor were 21 and the quotient 7?

To find the answer, just multiply the divisor with the quotient: 21 × 7 = 147

To prove this, let's compute 147 divided by 21: 147 21 = 7

How does it work?

Asking which value divided by 21 gives a result of 7 is equivalent to solving the following equation:

x 21 = 7

  1. We need to isolate x, so multiply both sides by 21: 21 x 21 = 21 × 7
  2. 21 x 21 is equivalent to 21 21 x , which simplifies to 1 x (or just x ).
  3. Thus: x = 21 × 7 = 147

So, if the divisor is 21 and the quotient is 7, the dividend is 147.
