1 meter has 100 CENTImeters.
now, 85cm is not longer than 1 meter clearly, because 100 cm > 85 cm.
so one can say, that is 1 meter is longer by 15cm instead.
100 - 85 = 15.
Answer:
1 meter has 100 cm
85cm is less them 100cm
Do subtraction. Like this:
100cm -85cm=
The answer is 15cm
Also, the question should be the other way.
