a metre length of cable is cut into 3 strips and the first strip is 3.42 and the second strip was 0.75
how long would the 3rd strip be ?

1 metre = 100 cm
if the two strips that you give without units are 3.42 cm and 0.75 cm then the third strip is 100  3.42  .75
(I have a feeling you did not type the question exactly as it was stated)
