I had a piece of string 300 cm in length. I cut off three pieces, one of length 97 cm, one of length 53 cm and one of length 112 cm. What is the length of the piece of string that I had left?
To find the length of the piece of string that you had left, subtract the lengths of the three pieces you cut off from the original length.
Original length: 300 cm
Length of the first piece cut off: 97 cm
Length of the second piece cut off: 53 cm
Length of the third piece cut off: 112 cm
Length of the string left = Original length - Length of the first piece - Length of the second piece - Length of the third piece
= 300 cm - 97 cm - 53 cm - 112 cm
= 300 cm - 262 cm
= 38 cm
Therefore, the length of the piece of string that you had left is 38 cm.
To find the length of the piece of string that you had left, you need to subtract the lengths of the three pieces you cut off from the original length of the string.
Step 1: Start with the original length of the string, which is 300 cm.
Step 2: Subtract the length of the first piece you cut off, which is 97 cm.
300 cm - 97 cm = 203 cm
Step 3: Subtract the length of the second piece you cut off, which is 53 cm.
203 cm - 53 cm = 150 cm
Step 4: Subtract the length of the third piece you cut off, which is 112 cm.
150 cm - 112 cm = 38 cm
Therefore, the length of the piece of string that you had left is 38 cm.
