A 10 2/3 inch long pipe is cut into 8 equal length pieces, how long is each piece​
storchak [24]

Answer:

\frac{4}{3} inches

Step-by-step explanation:

The total length of pipe is  10  2/3rd inches

It is cut into 8 equal pieces

We need to divide total length by 8 to get length of each piece. First, we have to convert mixed number (total length) to improper fraction by using formula shown below:

a\frac{b}{c}=\frac{(a*c)+b}{c}

So,

10\frac{2}{3}=\frac{32}{3}

Each piece length is:

\frac{\frac{32}{3}}{8}\\=\frac{32}{3}*\frac{1}{8}\\=\frac{32}{24}\\=\frac{4}{3}

So, each piece is \frac{4}{3} inches
