How Sandy bought 3 over 4 yard of red ribbon and 2 over 3 yard of with ribbon to make some hair bows altogether how many yards of ribbon did she buy?

To find out how much ribbon Sandy bought in total, you need to add the two fractions: ( \frac{3}{4} ) yard of red ribbon and ( \frac{2}{3} ) yard of white ribbon. First, find a common denominator, which is 12. Converting the fractions, ( \frac{3}{4} ) becomes ( \frac{9}{12} ) and ( \frac{2}{3} ) becomes ( \frac{8}{12} ). Adding these gives ( \frac{9}{12} + \frac{8}{12} = \frac{17}{12} ), or 1 yard and ( \frac{5}{12} ) yard of ribbon in total.
