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?
(Hint: convert data in cm.)
Answers
Given :
• A cloth of 2 m 15 cm is needed to stitch a shirt.
To find :
• How many shirts can be stitched out of 40 m cloth and how much cloth will be left
Concept :
Here, we have to find the no. of shirt which can be stiched out of 40 m cloth and how much cloth will be left. So, firstly we will convert the length of cloth from m into cm. And then divide the total cloth by cloth required for 1 shirt. The value of quotient after dividing will be the number of shirts which can be stitched out of 40cm cloth and the remainder will be the remaining cloth.
Solution :
Converting the length of the cloth required for one shirt into cm :-
As we know,
• 1 m = 100 cm
So, to convert the value from m into cm multiply it by 100.
→ 2 m 15 cm
→ 2 m = 2 × 100 = 200 cm
→ Now, add 200 cm and 15 cm :-
→ 200 + 15 = 215 cm
Therefore, Length of cloth required for one shirt = 215 cm
Now, converting the length of the total cloth :-
→ 40 m = 40 × 100 = 4000 cm
Therefore, the length of the total cloth = 4000 cm
Number of shirts which can be made from the 4000 cm cloth = Total cloth ÷ Cloth required for one shirt
→ No. of shirts = 4000 ÷ 215
→ No. of shirts = 18.60
→ On rounding it off, we get :-
→ No. of shirts = 18
Therefore, number of shirts = 18
The length of remaining cloth left :-
→ Remainder = 130 cm
Therefore, length of the remaining cloth = 130 cm
