Answer 1

40-6*1,8-10,2=40-10,8-10,2=40-21=19м осталось

Answer 2

Calculating Remaining Fabric

To calculate the remaining fabric, we can start by finding the total length of fabric and then subtracting the lengths used for the children's sheets and the remaining fabric for the volochki.

Given: - Total length of fabric = 40 m - Length of fabric used for 6 children's sheets = 6 * 1.80 m - Length of fabric used for volochki = 10.20 m

Calculation

The total length of fabric used for the children's sheets is 6 * 1.80 = 10.80 m. The total length of fabric used for the volochki is 10.20 m.

Now, we can calculate the remaining fabric: Total length of fabric - (Length used for children's sheets + Length used for volochki) = 40 - (10.80 + 10.20) = 18 m.

Answer

The remaining length of fabric is 18 meters.
