Three plus the reciprocal of a number equals 7 divided by that number.  What is the number?
Let's call the unknown number x. Then we can translate the words into an equation: 3 + 1/x = 7/x. To solve for x, we need to get rid of the fractions. We can do this by multiplying both sides of the equation by x, the lowest common denominator. This gives us 3x + 1 = 7. Simplifying, we get 3x = 6. Dividing both sides by 3, we get x = 2.
