Equation to find number:
- 3 = 
Number's value: n = 
Step-by-step explanation:
Let n be the unknown number.
The reciprocal basically makes the number (n in this case) a fraction. So, that being said, the reciprocal of n would be
.
The difference of three and the reciprocal of a number (
) would be
- 3.
The quotient of 20 and the number (n) would be
.
So, with this information we've gathered so far, we can come up with an equation to find what the number equals.
Equation:
- 3 = 
To find what the number equals we must solve the equation.
