Answer:
Step-by-step explanation:
We have to count from 668 to 900. Basically we have to reach from 668 to 900.
This could be similar to jumping on a number line from 668 to 900.
We could use ones, tens and hundreds to do so.
If we take two jumps of 100 from 668, then,
, we reach 868.
If we take a jump of three tens from 868, then,
, we reach 898.
If we take a jump of two ones, then,
, hence, we reach 900.
Thus, we have to take two jumps of 100, three jumps of ten and two jumps of one to reach 900 from 668.
