Question

Miguel has a piece of string that is 3m and 25m long. He cut apiece off and it to tie around his sleeping bag. Now his original piece is only 1m and 46cm long. How long is the piece of string Miguel cut off?

Answer 1

Convert 46 cm into meters. There are 100 cm in one meter, so divide 46 by 100 to find how many meters are in 46 cm.
46/100 = .46

Subtract 3m - 1m = 2m.
Now subtract 25m - .46m = 24.54m.

Add 2 + 24.54 = 26.54.
The piece of string Miguel cut off is 26.54 meters.
