The problem requires adding the mixed numbers and finding both the exact and estimated sums.**Problem:**"Add. Find the exact sum and an estimated sum."\[\begin{array}{c}20 \frac{1}{8} \\+ 18 \frac{1}{4} \\\hline\end{array}\]**Steps for Solution:**1. **Exact Sum:** - Convert the fractions to have a common denominator. - \(\frac{1}{8}\) and \(\frac{1}{4}\) need to be combined. - \(\frac{1}{4}\) can be expressed as \(\frac{2}{8}\). - Add the fractions: \(\frac{1}{8} + \frac{2}{8} = \frac{3}{8}\). - Add the whole numbers: \(20 + 18 = 38\). - Combine the whole number and the fraction: \(38 \frac{3}{8}\).2. **Estimated Sum:** - Round each mixed number to the nearest whole number. - \(20 \frac{1}{8}\) is approximately 20. - \(18 \frac{1}{4}\) is approximately 18. - Estimated sum: \(20 + 18 = 38\).In summary, the exact sum is \(38 \frac{3}{8}\), and the estimated sum is 38.
