Mother uses 2.5 metres of cloths to sew a complete dress.
How many complete dresses can she sew from a bolt of cloth 42 m?
And how much cloth will remain? Give answer in cm.
My problem is how do I work out this problem with the help from you.
42 / 2.5 = 16.8
She can make 16 dresses with 0.8 left over.
0.8 * 2.5 = 2 meters = 200 centimeters left over
On the run
To solve this problem, you need to divide the total length of the cloth by the length required to sew one complete dress and then determine the remaining cloth.
1. Determine the length required to sew one complete dress:
- We are given that the mother uses 2.5 meters of cloth to sew one complete dress.
2. Divide the total length of the cloth by the length required for one complete dress:
- The total length of the cloth is given as 42 meters.
- Divide 42 meters by 2.5 meters to find out how many complete dresses can be sewn.
- Calculation: 42 / 2.5 = 16.8 complete dresses
3. Determine the remaining cloth:
- We need to find out how much cloth will remain after sewing 16 complete dresses.
- Subtract the length of cloth used for the complete dresses from the total length of the cloth.
- Calculation: 42 - (2.5 * 16) = 42 - 40 = 2 meters
4. Convert the remaining cloth to centimeters:
- Since the answer needs to be given in centimeters, we need to convert the remaining cloth from meters to centimeters.
- There are 100 centimeters in 1 meter.
- Multiply the remaining cloth in meters by 100 to convert it to centimeters.
- Calculation: 2 meters * 100 = 200 centimeters
Therefore, the mother can sew 16 complete dresses from a bolt of cloth that is 42 meters long. After sewing 16 complete dresses, there will be 200 centimeters (or 2 meters) of cloth remaining.
