A 40 meters rope was cut into 2 parts in the ratio of 2:3. How long is the shorter part?
assistant
How many parts were cut? ** The rope was cut into 2 + 3 = <<2+3=5>>5 parts.
How long is each part? ** So each part is 40/5 = <<40/5=8>>8 meters long.
How long is the shorter part? ** Since the shorter part is consists of 2 parts, then it is 8 x 2 = <<8*2=16>>16 meters long.
