Howard cuts 54 centimeters off of a 1 - meter board. how much of the board does Howard have left?

There are 100 centimeters in 1 meter, so 54 centimeters subtracted from 100 centimeters (1 meter) is

100-54=46

so 46 centimeters remain, or 46/100 of the board which is really 23/50 of the board.

So basically, your possible answers:

46 centimeters

0.46 meters

46% of the original board

23/50 of the original board
