Question

В куске 40 м полотна. От него отрезали полотна на 6 детских простыней, по 1 м 80 см на каждую, и на наволочки 10 м 20 см. Сколько метров полотна осталось? Реши в два способа.

Answer 1

ТОЛЬКО В ОДИН СПОСОБ
40м-4000см
1)4000см-(1м80см х 6)=2920см
2)2920см-10м20см=1900см
Ответ:1900см полотна осталось

Answer 2

Solution 1: Subtraction Method

To find out how much fabric is left after cutting 6 bed sheets and some pillowcases, we can use the subtraction method.

1. Calculate the total fabric used for the bed sheets: - Each bed sheet is 1 meter 80 centimeters long. - Total length of fabric used for 6 bed sheets = 6 * 1 meter 80 centimeters.

2. Calculate the total fabric used for the pillowcases: - Each pillowcase is 10 meters 20 centimeters long. - Total length of fabric used for pillowcases = 10 meters 20 centimeters.

3. Calculate the total fabric used: - Add the fabric used for bed sheets and pillowcases.

4. Subtract the total fabric used from the original length to find the remaining fabric.

Let's calculate each step.

Step 1: Calculate the total fabric used for the bed sheets

Each bed sheet is 1 meter 80 centimeters long. Therefore, 6 bed sheets * 1 meter 80 centimeters = 6 * 1 meter 80 centimeters.

Step 2: Calculate the total fabric used for the pillowcases

The fabric used for pillowcases is 10 meters 20 centimeters.

Step 3: Calculate the total fabric used

Add the fabric used for bed sheets and pillowcases.

Step 4: Subtract the total fabric used from the original length to find the remaining fabric

Subtract the total fabric used from the original length of 40 meters.

Let's proceed with the calculations.

Solution 2: Conversion to Meters

Another way to solve this problem is by converting all measurements to meters and then performing the calculations.

1. Convert all measurements to meters. 2. Calculate the total fabric used for the bed sheets and pillowcases in meters. 3. Subtract the total fabric used from the original length to find the remaining fabric in meters.

Let's proceed with the calculations using both methods.
