Question

Cierra has 2 5/8 meters of yarn that she wants to cut into 1/2 - meter lengths. How many half meter lengths of yarn will Cierra have?

Answer 1

Answer:

5 pieces (with a leftover of 1/4 meters).

Explanation:

$\begin{gathered} \text{Full length of yarn Cierra has}=2\frac{5}{8}\text{ meters} \\ \text{Length of each piece}=\frac{1}{2}\text{ meters} \end{gathered}$

To determine how many half meter lengths of yarn Cierra will have, we divide:

$\begin{gathered} \text{Number of half lengths=2}\frac{5}{8}\div\frac{1}{2} \\ =\frac{21}{8}\times\frac{2}{1} \\ =\frac{42}{8} \\ =5\frac{2}{8} \\ =5\frac{1}{4}\text{ pieces} \end{gathered}$

Therefore, Cierra will have exactly 5 pieces of half-meter lengths of yarn.
