Becca had
of a yard of ribbon to use for her crafts projects. She used
of a yard to make a bow. How much ribbon, r, does Becca have left?
Set up an equation and solve.
Since Becca had a certain amount of ribbon and used a certain amount, we can subtract the used amount from the initial amount to find out how much ribbon she has left.
Let's use the following representations:
- A = initial amount of ribbon Becca had
- B = amount of ribbon Becca used
- r = amount of ribbon Becca has remaining
We are given that Becca had " of a yard" of ribbon, so we can represent this as:
A =
We are also given that Becca used " of a yard" of ribbon, so we can represent this as:
B =
To find how much ribbon Becca has left, we need to subtract the used amount from the initial amount:
r = A - B
After setting up the equation, we can solve it by substituting the given values for A and B and evaluating the expression.
