Marisela cut four equivalent lengths of ribbon. Each was 5 eighths of a yard long. How many yards of ribbon did she cut? Express
kakasveta [241]

Answer:

2\frac{1}{2} yards.

Step-by-step explanation:

Please find the attachment.  

We have been given that Marisela cut four equivalent lengths of ribbon. Each was 5 eighths of a yard long.    

To find yards of ribbon cut by Marisela, we will multiply 4 by 5 eighths of a yard (5/8).

\text{Total ribbon cut by Marisela}=4\times \frac{5}{8}

\text{Total ribbon cut by Marisela}=\frac{4\times 5}{8}

\text{Total ribbon cut by Marisela}=\frac{20}{8}

Express answer as the sum of whole number and the remaining fractional units:

\text{Total ribbon cut by Marisela}=\frac{16+4}{8}

\text{Total ribbon cut by Marisela}=\frac{16}{8}+\frac{4}{8}

\text{Total ribbon cut by Marisela}=2+\frac{4}{8}

\text{Total ribbon cut by Marisela}=2\frac{4}{8}

Therefore, Marisela cut 2\frac{4}{8} yards of ribbon.
