Question 5.
Vedika has 23.5 metres of cloth. She used it to make 5 curtains of equal size. If each curtain required 4 metres 25 cm to make, how much cloth is left over?
Solution:
We know, that 1 m = 100 cm
Cloth required to make 1 curtain = 4 m 25 cm
= 4 m + 25/100 m
= 4 m + 0.25 m
Maharashtra Board Class 6 Maths Solutions Chapter 5 Decimal Fractions Practice Set 16 7
= 4.25 m
∴ Cloth required to make 5 curtains = 5 × 4.25
Maharashtra Board Class 6 Maths Solutions Chapter 5 Decimal Fractions Practice Set 16 8
= 21.25 m
Cloth remaining with Vedika = Total cloth with Vedika – Cloth used
= 23.5 m – 21.25 m

= 2.25 m
∴ The length of cloth remaining with Vedika is 2.25 m.
