#### Answer

The number we need to find is 72.

#### Work Step by Step

Let X represent the number. Two-thirds of the number means $\frac{2}{3}$ $\times$ X. $\frac{2}{3}$ $\times$ X = $\frac{2X}{3}$ We know that two-thirds of the number equals 48. So, $\frac{2X}{3}$ = 48. Multiply both sides by 3. 2X = 144 Divide both sides by 2. X = 72
