5/8 part of 40m long cloth was sold. How many metres of cloth was left?

well, 1/8 of 40 is 5, so ...

To find out how many meters of cloth were left after selling 5/8 of a 40-meter long cloth. We can follow the steps below:

Step 1: Calculate the amount of cloth sold by multiplying the length of the cloth by the fraction sold:
5/8 * 40m = (5 * 40m) / 8 = 200m / 8 = 25m

Step 2: Subtract the amount sold from the original length of the cloth to find the amount left:
40m - 25m = 15m

Therefore, there were 15 meters of cloth left.

To find the number of meters of cloth that was left, we can use a simple calculation.

Step 1: Calculate the amount of cloth that was sold.
Since 5/8 of the cloth was sold, we need to find the fraction of 40m that represents.
The calculation is: (5/8) * 40m = 25m

Step 2: Calculate the amount of cloth that was left.
To find this, we subtract the amount sold from the total amount.
The calculation is: 40m - 25m = 15m

Therefore, there were 15 meters of cloth left.
