A welder cuts 3/4m long pieces from a steel rod that is 5 and 3/4m long.Write an expression for the number of lengths that can be cut from the rod

To find out how many pieces of ribbon can be cut from a length of 4 and a half meters, we need to follow these steps:

1. Convert the length of 4 and a half meters to centimeters. Since there are 100 centimeters in 1 meter, the length in centimeters would be:

4.5 meters * 100 centimeters/meter = 450 centimeters.

2. Divide the total length in centimeters by the length of each ribbon piece.

450 centimeters / 4.5 centimeters = 100.

Therefore, you can cut 100 pieces of ribbon, each 4.5 cm long, from a length of 4 and a half meters.
