We have the given number = 660
 Now, explain the relationship of 6s in the given number.
 => 6 = hundreds
 => 6 = tens
 => 0 = ones
 This is also another form:
 => 6 = 600
 => 6 = 60,
 now, notice that the first value of 6 in the leftmost side is 10 times higher than the next number 6.
 => 60 x 10 = 600.
 Thus, 600 is 10 times greater than 60 and vice versa.
