What value divided by 90 equals 21?

In other words, what would the dividend be if the divisor were 90 and the quotient 21?

To find the answer, just multiply the divisor with the quotient: 90 × 21 = 1890

To prove this, let's compute 1890 divided by 90: 1890 90 = 21

How does it work?

Asking which value divided by 90 gives a result of 21 is equivalent to solving the following equation:

x 90 = 21

  1. We need to isolate x, so multiply both sides by 90: 90 x 90 = 90 × 21
  2. 90 x 90 is equivalent to 90 90 x , which simplifies to 1 x (or just x ).
  3. Thus: x = 90 × 21 = 1890

So, if the divisor is 90 and the quotient is 21, the dividend is 1890.
