Jolene

Jolene is cutting a strip of yarn that is 11/12 inch long pieces that are 2/12 inch long for a collage. How many complete pieces can she make?

Correct answer:

n =  5

Step-by-step explanation:

$$\begin{gathered} a=\frac{11}{12}\doteq 0.9167\text{in} \\ b=\frac{2}{12}=\frac{1}{6}\doteq 0.1667\text{in} \\ {n}_1=a/b=\frac{11}{12}/\frac{1}{6}=\frac{11}{12}:\frac{1}{6}=\frac{11}{12}\cdot \frac{6}{1}=\frac{11\cdot 6}{12\cdot 1}=\frac{66}{12}=\frac{11}{2}=5\frac{1}{2}=5.5 \\ n=\lfloor n_1\rfloor =\lfloor 5.5\rfloor =5 \end{gathered}$$
