To round a number to the nearest tenth we look at the hundredth place
If the digit in the hundredth place is 5 or greater than 5, then we add the digit in the tenths place by 1 and remove the digits right to it
If the digit in the hundredth place is less than 5, we removed all the digits right to the tenth digit
Since the number is 50.26
The digit in the hundredth place is 6 (greater than 5)
Then add the digit in the tenths place by 1 and remove the digit in the hundredth place
The number is 50.3
50.26 is rounded to 50.3 to the nearest tenth
