Answer 1

$\large\bf\underline \orange{Given:-}$

2m 30cm cloth is needed to stitch a frock.

length of total cloth = 45m

$\large\bf\underline \orange{To \: find:-}$

45 m cloth, how many frocks of the same size can be stitched and how much cloth will remain unused?

$\huge\bf\underline \green{Solution:-}$

Cloth required to stitch 1 frock = 2m 30 cm

• 1m = 100cm

⠀⠀⠀⠀⠀➝ 2 × 100 + 30cm

⠀⠀⠀⠀⠀➝ 200 + 30

⠀⠀⠀⠀⠀➝ 230cm

Length of total cloth = 45m

⠀⠀⠀⠀⠀➝ 45 × 100cm

⠀⠀⠀⠀⠀➝ 4500 cm

Number of frocks can be stitched = 4500/230 = 450/23
