Distance travelled by train = 4.19 kilometers
Distance travelled by bus = 6.456 kilometers
Distance travelled by car = 11.2 kilometers
Distance travelled by walk = 0.231 kilometers
Total distance travelled = (4.19 + 6.456 + 11.2 + 0.231) kilometers
Step 1: Align the decimal numbers according to their place values one below the other
T O . t h th
4 . 1 9 0+ 6 . 4 5 6+1 1 . 2 0 0+ 0 . 2 3 1−−−−−−
Step 2: Add each column of digits, starting on the right.
If the sum of a column is more than 10, carry digits to the next column on the left

Finally, place the decimal point of the sum vertically below the other decimal points.
Hence, John travelled 22.077 kilometers in total.
