Question

Another question... this was all the information I was given and I'm a tad confused as to how to go about solving it... help please??? Thank you so much!!!
Julia needs to cut a 15m rope into 20 equal pieces. Calculate the length of each piece in cm

Answer 1

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.

Answer 2

The rope needs to be cut into 20 pieces, so 15/20, this will give you 3/4 of a meter per piece. Multiply 100 (100 cm in a meter), .75*100= 75 centimeters in a piece...
