Answer:
13.261 < 13.265
Explanation:
In order to compare two numbers, you must look at each place value.
Start from the leftmost value (the tens place):
13.261 and 13.265
They are the same, so we move one place over.
13.261 and 13.265
Still the same, so we move on again
13.261 and 13.265
Still the same, repeat
13.261 and 13.265
Repeat
13.261 and 13.265
These are not the same, so now we compare 1 and 5.
On a number line, 1 is more left on the line than 5, so 1 < 5
Thus, 13.261 <13.265
