Which is larger 1.403 or 1.4?

Answer 1

To compare numbers:

1. Start with the left-most place value column that has a non-zero digit that occurs in the numbers;
2. Compare the digits in this column (if a column is empty it should be considered as containing a zero);
3. if the digits are the same, move right a place value column and repeat from step 2
4. The larger number is the number which has the larger digit.

With 1.403 and 1.4 the left most place value column is the ones column (just left of the decimal point)

they both have a 1 here, so check the next column to the right:

they both have a 4 here, so check the next column right:

1.403 has a 0 but 1.4 has nothing, which is taken as a 0; they both have a 0 here, so check the next column right:

1.403 has a 3 but 1.4 has nothing, which is taken as a 0; 3 is greater than 0, so 1.403 is greater than 1.4

1.403 is greater than 1.4
