How many pieces 3 and three fifths in. long can be cut from 28 metal rods each 15 in. long? disregard waste.

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:

2. You know that each metal rod is 15 inches long. Then, you must divide the lenght of each one by 3.6:

3. The waste is 0.16, therefore, you obtain 4 pieces from a metal rod. The total pieces obtained from 28 metal rods are:

116 whole pieces

Step-by-step explanation:

We have a 28 metal rods that are 15 inches long each, out of which we need to cut inches long metal rods.

Firstly, we will convert the mix fraction into improper fraction and then divide the total length of the rod by it.

inches = inches

Dividing the total length of rod by this length and multiplying it by 28 to get:

= =

Therefore, 116 whole pieces can be cut from the given length of rod.
