What is Visualizing Fraction Addition/Subtraction about?

Maribel walks various fractions of a kilometer on errands for her teacher. To determine the total distance walked, we must add the fractions. When adding similar fractions, only the numerators are added and the common denominator is kept. For example, 3/10 + 4/10 = 7/10 kilometers. Subtracting fractions follows the same process, but the numerators are subtracted instead of added. Visualizing fractions on a number line can help solve word problems that involve adding or subtracting fractions.
