Solution:
The given question is to illustrate number bond to make hundred and solve 190+ 460
190 is closer to 200 .So to make it 200 we need 10, take it from 460.
Now we have 190+10 = 200 and 460-10 = 450.
Now, Adding them 200 + 450 = 650.
Or In other way, 19 tens and 46 tens is equal to 65 tens which 650
