2 m 15 cm per shirt
40 m cloth

1 m = 100 cm

2m * 100cm/m = 2 * 100cm = 200 cm
200 cm + 15 cm = 215 cm per shirt

40 m * 100cm/m = 40 * 100cm = 4,000 cm
4,000 cm / 215cm = 18.60

18 shirts can be made.

215 cm * 18 = 3870 cm
4,000 - 3,870 = 130 cm cloth left.

1 m = 100 cm
cloth needed to stitch a shirt = 2 m 15 cm  = 215 cm
cloth available 40 m = 4000 cm
No.of shirts can stitch = Total cloth available / cloth needed to stitch a shirt
= 4000/215
= 18.6046
18 shirts can be stitched from 40 m cloth
18 × 215 = 3870
cloth remains= 4000 - 3870 = 130 cm = 1.3 m
