Answer 2

Problem Analysis

We are given a piece of fabric that is 40 meters and 5 decimeters long. We need to determine how many costumes can be made from this piece of fabric, with each costume requiring 4 meters and 5 decimeters of fabric.

Solution

To find the number of costumes that can be made, we need to divide the length of the fabric by the length required for each costume.

The length of the fabric is 40 meters and 5 decimeters, which can be written as 40.5 meters.

The length required for each costume is 4 meters and 5 decimeters, which can be written as 4.5 meters.

To find the number of costumes, we divide the length of the fabric by the length required for each costume:

Number of costumes = Length of fabric / Length required for each costume

Substituting the values, we have:

Number of costumes = 40.5 meters / 4.5 meters

Simplifying the division, we get:

Number of costumes = 9

Therefore, it is possible to make 9 costumes from this piece of fabric.

Answer

You can make 9 costumes from this piece of fabric.
