Solution:
Given that,
Robin is making bows to sell at her mother's yard sale
From given,
[tex]\text{Length of red ribbon } = \frac{3}{4}\ foot\\\\\text{Length of blue ribbon } = \frac{2}{3}\ foot[/tex]
What is the ratio of the length of red ribbon to blue ribbon?
[tex]Red : blue = \frac{3}{4} : \frac{2}{3}\\\\Red : blue = \frac{3 \times 3}{4 \times 3} : \frac{2 \times 4}{3 \times 4}\\\\Red : blue = \frac{9}{12} : \frac{8}{12}\\\\Red : blue = 9 : 8[/tex]
Thus ratio of length of red ribbon to blue ribbon is 9 : 8
