Question

Addison used 5/6yard of ribbon to decorate a photo frame. she used 1/3 yards of ribbon to decorate her scrapbook. which fraction strip should Addison trade for the 1/3 strip in order to find how many yards of ribbon she used in all

Answer 1

1/3 will become 2/6.

Steps in adding fraction.
Step 1. Make sure that the denominators are the same:
5/6 + 1/3      * 6 and 3 are the denominators. they are not the same. however, 6 is twice the number of 3. Thus, multiply 2 to the numerator and denominator of 1/3

1/3 * 2/2 = 2/6

5/6 + 2/6

Step 2. Add the numerators. Put the sum above the common denominator.

(5+2) / 6 = 7/6

Step 3. Simplify the fraction.

7/6 = 1 1/6 

Addison used 1 1/6 yards of ribbon in all.
