Argh! My answer was erased!
We need to cut a 15m rope into 20 equal pieces. Written mathematically, it is as follows:
15/20 = length of rope segment in meters (a)
15/20 = a
Simplify
3/4 = a
In meters, each rope segment is 3/4m long. But, we don't want meters. We want centimeters.
100 cm = 1 m
3/4(100) = length of rope segment in centimeters (x)
3/4(100) = x
300/4 = x
75 = x
Each segment of rope is 75 cm long.
