Question

Ravi bought 3m 60cm length of pant cloth. He gave 1m 20 cm of cloth to his younger brother. What is the length of the remaining cloth?

Answer 1

Hint: The length of the remaining cloth is given by the length of pant cloth bought minus the length of cloth given to his younger brother. After that substitute, the value of the total length of pant cloth bought and the length of cloth given to his younger brother. The difference will be the desired result.

Complete step by step answer:
Given: - Total length of pant cloth $= 3m \, 60 cm$
Cloth gave to the younger brother $= 1m \, 20cm$
The length of the remaining cloth is given by the length of pant cloth bought minus the length of cloth given to his younger brother.
Length of the remaining cloth = (Total length of pant cloth) - (Length of cloth given to his younger brother)
Substitute the values of the total length of pant cloth bought and the length of cloth given to his younger brother,
Length of the remaining cloth = $3m \, 60cm – 1m \, 20cm$
Subtract the values on the right side,
Length of the remaining cloth =$ 2m \, 40cm$

Hence, the length of the remaining cloth is 2m 40cm

Note:
Subtraction is one of the four basics of arithmetic operations. The subtraction process gives the difference between the two numbers. It is the inverse of the addition operation. The notation used to describe the subtraction is “minus (-)”. The subtraction process starts from the unit digit, then ten’s digits, the hundreds digit, and it continues the process towards the highest digit places. If the minuend is greater than the subtrahend, the subtraction process is easy, and we can subtract directly. If the minuend is lesser than the subtrahend, then borrow the number from the next highest digit of the minuend to continue the subtraction process.
