Answer:

\huge\boxed{\frac{2}{15} \text{        yards}}

Step-by-step explanation:

We have a board that is \frac{2}{3} yards long. If we want to cut the board into 5 <em>equal pieces</em>, we must divide \frac{2}{3}  by 5.

\frac{2}{3} \div 5

5 is the same thing as \frac{5}{1}, so:

\frac{2}{3} \div \frac{5}{1}

To divide a fraction by a fraction, we multiply by the reciprocal.<em> </em>This means we take the reciprocal of \frac{5}{1} and multiply the two fractions.

The reciprocal of \frac{5}{1}  is \frac{1}{5} - we swap the numerator and denominator.

\frac{2}{3} \cdot \frac{1}{5}

Multiply the numerator and denominators to get our final fraction:

2\cdot 1 = 2\\3 \cdot 5 = 15\\\\\frac{2}{15}

Hope this helped!

Order of operations rules (PEMDAS) govern here.  Anything inside parentheses must be done first, followed by exponentiation, mult. and div., and add. and subtr. last.

Add 2+5 first:    5 + 2*{(7)*5 + 5}

Perform the work shown inside the brackets {  and  }:  5 + 2*{40}

Perform the indicated mult.:  5 + 80
