the other one i wrong (i don't know if this is right) what i did for the cm was but what i did for the cm was i put 10 in the missing spot because if i add 1+10+5 i get 16cm so thats what i put there.
for mm i put 100 mm because 10 mm is 10 cm so yea and i put 19mm because if i take off the 9 so i had a 10. it would me 1cm and if i added the 9 part to the 1 in 41 the i have another cm and 40 =4cm so if i added them all up 41+19+100 the i got 16cm so that how i did it and al so the reson why i put 100mm and all is because 10mm is 1cm.
