Imagine a decimal number, for example, 123 (hundred and twenty-three). Each digit has a corresponding place-value; the right-most digit has the place-value 1, the next digit (counting from the right) has the place-value 10, the next digit hast eh place-value 100. The right-most position (where the digit "3" is in this example) is in the position of least value - the least significant position. When several bits represent an integer, the situation is the same, except that the numbers are in base-2 instead of base-10 (each position is worth twice as much as the position to the right). But you still have the concept of place-value, and the digit that represents the 1's position is the "least significant bit".
The places are always the same no matter what the digits are. The value is obtained by multiplying the place times the digit. Starting from the right, the places in an 8-digit number are ones, tens, hundreds, thousands, ten thousands, hundred thousands, millions and ten millions.

The value of a digit depends on its position as well as its face value.
03.8 and 3.80 have the same value.
Since the integer parts are the same (zero in each case), compare the first digit after the decimal point. The number with the smallest digit here is the smallest. If the first digit after the decimal point is the same, compare the second digit, etc.

Don't make it more complicated than it is. The place value is decided only by how far the digit is from the decimal point. It has nothing to do with what digit is in it.
They are the same because they are both multiplication. They also can be the same if the two digit number times by the one digit number equals a three digit number. They are different because the 3 digits number will obviously produce a higher product.
