robin needed 3 2/3 feet of thread to finish a pillow she was making. if she has 2 times as much thread as she needs, what is the length of the thread she has?
Answer:
\(7\frac{1}{3}\) feet.
Step-by-step explanation:
We have been given that Robin needed 3 2/3 feet of thread to finish a pillow she was making. We are asked to find the length of thread, if she has 2 times as much as thread as she needs.
First of all, we will convert \(3\frac{2}{3}\) into improper fraction as:
\(3\frac{2}{3}\rightarrow \frac{3*3+2}{3}=\frac{9+2}{3}=\frac{11}{3}\)
Two times the length of thread would be:
\(2\times\frac{11}{3}\)
\(\frac{2\times11}{3}\)
\(\frac{22}{3}\)
\(\frac{3*7+1}{3}\)
\(7\frac{1}{3}\)
Therefore, Robin had \(7\frac{1}{3}\) feet of thread.
