<human>:  A 1165 cm long rope is cut into 154 pieces. 150 of the pieces are equally sized and the remaining pieces are 100mm each. Find the length of each of the equal pieces in millimeters.
<bot>: How many millimeters are in 1165cm? ** Each cm contains 10mm so 1165cm is 1165*10 = <<1165*10=11650>>11650mm
How many 100mm pieces are there? ** 154-150 = <<154-150=4>>4 pieces of the rope are 100mm each in length
How many millimeters are in the 4 100mm pieces? ** The 4 pieces have a total length of 4*100 = <<4*100=400>>400mm
How many millimeters are left? ** There is a length of 11650-400 = <<11650-400=11250>>11250mm left
How long are the 150 pieces? ** 11250 mm into 150 equal pieces will give each piece as 11250/150 = <<11250/150=75>>75mm long
