Becca had 13/15
of a yard of ribbon to use for her crafts projects. She used 3/7
of a yard to make a bow. How much ribbon, r, does Becca have left?
Set up an equation and solve.
The equation can be set up as follows:
r = 13/15 - 3/7
In order to solve this equation, find a common denominator for 15 and 7, which is 105.
Convert the fractions to have a denominator of 105:
r = (13/15) * (7/7) - (3/7) * (15/15)
Simplify:
r = 91/105 - 45/105
Combine the fractions:
r = (91 - 45) / 105
Simplify further:
r = 46/105
Therefore, Becca has 46/105 yards of ribbon left.
