3 pieces of ribbon, each 85 cm long, are cut from a length of ribbon 3 m long. What is the length of the remaining piece of ribbon?
what is 3*100cm-3*85cm ?
45
To find the length of the remaining piece of ribbon, we need to subtract the total length of the three pieces of ribbon from the original length of 3 meters.
The length of each piece of ribbon is 85 cm, and since there are three pieces, the total length of ribbon used is 85 cm x 3 = 255 cm.
To convert centimeters to meters, we divide by 100: 255 cm ÷ 100 = 2.55 m.
Finally, we subtract the total length used from the original length: 3 m - 2.55 m = 0.45 m.
Therefore, the length of the remaining piece of ribbon is 0.45 meters.
To find the length of the remaining piece of ribbon, we need to subtract the total length of the three pieces of ribbon from the original length of the ribbon.
Given:
Length of the original ribbon = 3 m = 300 cm
Length of each piece of ribbon = 85 cm
To find the total length of the three pieces of ribbon, we need to multiply the length of one piece of ribbon by the number of pieces, which is three:
Total length of the three pieces of ribbon = 85 cm/piece * 3 pieces = 255 cm
Now, we can find the length of the remaining piece of ribbon by subtracting the total length of the three pieces from the original length:
Remaining length of the ribbon = Original length - Total length of the three pieces
Remaining length of the ribbon = 300 cm - 255 cm
Remaining length of the ribbon = 45 cm
Therefore, the length of the remaining piece of ribbon is 45 cm.
