Question

Tina had 20 m 5 cm long cloth. She cuts 4 m 50 cm length of cloth from this for making a curtain. How much cloth is left with her?

Answer 1

$<b>$Your answer !!

Total length of cloth = 20m 5cm

=> 1m = 100cm

=> 20m = 20 × 100 = 2000cm

=> 2000cm + 5cm = 2005cm

Used cloth = 4m 50cm

=> 1m = 100cm

=> 4m = 4 × 100 = 400cm

=> 400cm + 50cm = 450cm

Cloth left behind = Total cloth - Used cloth

=> 2005cm - 450cm

=> 1555cm
