Hi!
First, let me say you can add infinite 0s to the right of a decimal, and it will still be the same value. Just like you can add infinite 0s to the left of a whole number and it will still be the same value.
47.
0.70, 0.07
Multiply both decimals by 100.
70, 7
Because 70 is greater than 7, 0.70 is greater than 0.07.
0.7 > 0.07
48.
0.36, 0.49
Multiply both decimals by 100.
36, 49
Because 36 is less than 49, 0.36 is less than 0.49.
0.36 < 0.49
49.
0.29, 0.24
Multiply both decimals by 100.
29, 24
Because 29 is greater than 24, 0.29 is greater than 0.24.
0.29 > 0.24
0.7 > 0.07
0.36 < 0.49
0.29 > 0.24
Hope this helps! :)
