The answer is 100 cm.

250 cm - 1 1/2 m = ?

1 1/2 m = 1 + 1/2 = 2/2 + 1/2 = (2 + 1)/2 = 3/2 = (3*5)/(2*5) = 15/10 = 1.5 m

1 m = 100 cm
1.5 m = 150 cm

250 cm - 1 1/2 m = = 250 cm - 150 cm = 100 m

A rope is 250 centimeters long. You need the rope to be 1 1/2 meters long. How many centimeters should you cut off?
