Question

pieces of 90 cm length have to be cut from 226 m long wire how many such probable pieces can be cut off

Answer 1

 are 100 cm in 1 m.
So with that, if you put 4.5 m  in cm you get 450 cm of ribbon.
Then divide 450 by 4.5 to see how many times you can take out 4.5 cm from the amount you have. 
450/4.5 = 100
So you can get 100 pices of ribbon each
