**To stitch a shirt, 2 m 15 cm cloth is needed. Out of 40 m cloth, how many shirts can be stitched and how much cloth will remain?**

To find out how many shirts can be stitched and how much cloth will remain, you can divide the total amount of cloth available by the cloth needed for each shirt and then find the remainder.

Cloth needed for one shirt = 2 meters 15 centimetersTotal cloth available = 40 meters

Now, calculate how many shirts can be stitched:

Number of shirts = Total cloth available / Cloth needed for one shirt Number of shirts = 40 meters / 2 meters 15 centimeters

First, convert 15 centimeters to meters (1 meter = 100 centimeters):

15 centimeters = 15 / 100 meters = 0.15 meters

Number of shirts = 40 meters / (2 meters + 0.15 meters)

Number of shirts = 40 meters / 2.15 meters

Number of shirts ≈ 18.60 shirts

Since you can't have a fraction of a shirt, you can stitch a maximum of 18 shirts from the 40 meters of cloth. Now, calculate how much cloth will remain:

Remaining cloth = Total cloth available - (Number of shirts stitched × Cloth needed for one shirt) Remaining cloth = 40 meters - (18 shirts × 2 meters 15 centimeters)

Remaining cloth = 40 meters - (18 shirts × 2.15 meters)

Remaining cloth ≈ 40 meters - 38.70 meters

Remaining cloth ≈ 1.30 meters

So, you can stitch 18 shirts, and 1.30 meters of cloth will remain. (1.30 meters = 1 meter 30 centimeter)
