A roll of wire is 8m 9cm long. If i cut it off into 9 pieces of equal length, what will be the length of each piece?
8m, 9 cm = 809 cm
number of pieces which are 9 cm long
= 809/9 = 89.88.. or appr 90 cm each
btw,
in the true usage of the metric system, one would not say
8m, 9cm
it would be either 809 cm or 8.09 m
the beauty of the metric system is that you don't have to mix units like in the old imperial system.
To find the length of each piece, you need to divide the total length of the wire by the number of pieces.
Step 1: Convert the given length to a single unit. The length of the wire is 8m 9cm. To add the lengths together, convert 9cm to meters. Since 1 meter is equivalent to 100 centimeters, divide 9cm by 100 to get the length in meters:
9cm / 100 = 0.09m
Now, the total length of the wire is:
8m + 0.09m = 8.09m
Step 2: Divide the total length by the number of pieces. Divide 8.09m by 9 to get the length of each piece:
8.09m / 9 = 0.898m (rounded to three decimal places)
Therefore, each piece of wire will be approximately 0.898 meters long.
