Luis has 3 1/3 yards of ribbon to use for two separate presents, one of which is very large. If Luis uses 2 1/2 yards to decorat

never [62]

Answer:

$\frac{5}{6}$ yards

Step-by-step explanation:

Luis had $3\frac{1}{3}$ yards of ribbon in total to use for two presents. For the first present Luis used $2\frac{1}{2}$ yards of the ribbon.

Since she had $3\frac{1}{3}$ yards in total and she used $2\frac{1}{2}$ yards from it, the amount of ribbon left for second present can be obtained by taking out(subtracting) $2\frac{1}{2}$ yards from $3\frac{1}{3}$ .

So, the number of yards of ribbon left for second present will be:

$3\frac{1}{3}-2\frac{1}{2}\\\\ =\frac{10}{3}-\frac{5}{2}\\\\ =\frac{10(2)-5(3)}{2 \times 3}\\\\ =\frac{20-15}{6}\\\\ =\frac{5}{6}$
