What value divided by 87 equals 90?

In other words, what would the dividend be if the divisor were 87 and the quotient 90?

To find the answer, just multiply the divisor with the quotient: 87 × 90 = 7830

To prove this, let's compute 7830 divided by 87: 7830 87 = 90

How does it work?

Asking which value divided by 87 gives a result of 90 is equivalent to solving the following equation:

x 87 = 90

  1. We need to isolate x, so multiply both sides by 87: 87 x 87 = 87 × 90
  2. 87 x 87 is equivalent to 87 87 x , which simplifies to 1 x (or just x ).
  3. Thus: x = 87 × 90 = 7830

So, if the divisor is 87 and the quotient is 90, the dividend is 7830.
