a ball of strings contains 13and half metres ,length of, 2,3 m :1,8m :95cm and 2,37m are cut off the remainder is divided into equal pieces each 32cm long, how many of these equal pieces are there
is it 2.3,1.8,2.37 or 2,3,1,8,2,37?
To find the number of equal pieces, we first need to calculate the length of the part that is cut off. Then, we subtract the cut-off length from the total length of the ball of strings. Finally, we divide the remaining length by the length of each piece to determine the number of equal pieces.
1. Calculate the length of the part that is cut off:
- 2 m = 200 cm
- 3 m = 300 cm
- 1.8 m = 180 cm
- 95 cm
- 2.37 m = 237 cm
Total length of the parts cut off = 200 cm + 300 cm + 180 cm + 95 cm + 237 cm
2. Find the remaining length of the ball of strings:
Total length of the ball of strings = 13.5 m = 1350 cm
Remaining length = Total length of the ball of strings - Total length of the parts cut off
3. Calculate the number of equal pieces:
Number of equal pieces = Remaining length / Length of each piece
Now, let's do the calculations:
Total length of the parts cut off = 200 cm + 300 cm + 180 cm + 95 cm + 237 cm = 1012 cm
Remaining length = 1350 cm - 1012 cm = 338 cm
Number of equal pieces = 338 cm / 32 cm = 10.5625
Since we can't have a fraction of a piece, we need to round down to the nearest whole number.
Therefore, there are 10 equal pieces.
