Answer: 112 pieces
Step-by-step explanation:
1. Rewrite
as a decimal. Divide the numerator and the denominator of the fractional part and add it to the integer part:
![3+0.6=3.6in](https://tex.z-dn.net/?f=3%2B0.6%3D3.6in)
2. You know that each metal rod is 15 inches long. Then, you must divide the lenght of each one by 3.6:
![pieces=\frac{15in}{3.6in}4.16](https://tex.z-dn.net/?f=pieces%3D%5Cfrac%7B15in%7D%7B3.6in%7D4.16)
3. The waste is 0.16, therefore, you obtain 4 pieces from a metal rod. The total pieces obtained from 28 metal rods are:
![total=4pieces*28=112pieces](https://tex.z-dn.net/?f=total%3D4pieces%2A28%3D112pieces)
