Work Step by Step

Given, At the annual Cub Scout Pinewood Derby competition, $\frac{3}{8}$ of the events were completed before lunch and $\frac{5}{8}$ after lunch. To find, Event that was completed after lunch than before lunch They are like fractions We need to subtract the competition before lunch from after lunch $\frac{5}{8}$ - $\frac{3}{8}$ Step 1 Subtract the numerators to find the numerator of the difference Step 2 Write the denominator of the like fractions as the denominator of the sum $\frac{5- 3}{8}$ = $\frac{2}{8}$ $\frac{2}{8}$ is not in lowest term to divide the numerator and denominator by common factor 2 $\frac{2}{8}$ = $\frac{1}{4}$ more of the events
