Question

Learn with an example v Sharon has a red ribbon and an indigo ribbon. The red ribbon is 6 1/4 inches long. The indigo ribbon is 6 1/4 inches longer than the red ribbon. How long is the indigo ribbon?

Answer 1

Let R be the length of the red ribon and let I be the length of the indigo ribbon. We have that the red ribbon is 6 1/4 inches long, then:

`R=6(1)/(4)=(25)/(4)`

Then, the indigo ribbon is 6 1/4 inches longer than the red ribbon. Then we have:

`I=R+6(1)/(4)`

therefore:

`I=(25)/(4)+(25)/(4)=(50)/(4)=(25)/(2)=12(1)/(2)`

finally, we have that the indigo ribbon is 12 1/2 inches long
