Question

Estimating in word problems with fractions. Rosa needs 5 1/4 of ribbon for a crafts project. She already has 2 7/8 of ribbon. How many more yards of ribbon does she need to buy?

Answer 1

Answer:

Rosa requires $2\frac{3}{8}\text{ yards}$ of ribbon to complete the project.

Step-by-step explanation:

We are given the following in the question:

Length of ribbon required for project =

$5\dfrac{1}{4}\text{ yards}$

Length of ribbon Rosa have =

$2\dfrac{7}{8}\text{ yards}$

Amount of ribbon required for the project =

Length of ribbon required for project - Length of ribbon Rosa have

$=5\dfrac{1}{4}-2\dfrac{7}{8}\\\\=\dfrac{21}{4}-\dfrac{23}{8}\\\\=\dfrac{42-23}{8}\\\\=\dfrac{19}{8}\\\\=2\dfrac{3}{8}\text{ yards}$

Thus, Rosa requires $2\frac{3}{8}\text{ yards}$ of ribbon to complete the project.
