Question

Olivia is making scarves. Each scarf will have 5 rectangles, and 2/5 of the rectangles will be purple. How many purple rectangles does she need for 3 scarves?

Answer 1

Just add 2/5+2/5+2/5.

Add: 2       2        2  ----- numerators
       ---- + ---- + ----- =?                                                     
        5        5       5   ------- denominators

Add your numerators first: 2+2+2=6 

Leave your denominators alone they are all 5 so that's ok.

Your answer will be 6
                              ------
                                 5

Hope I helped:)
