During addition, the result cannot have more digits to the right of the decimal point than either of the original numbers. Since there is only 1 digit after the decimal point in 0.8 so the result 7.48 should be rounded off to 1 decimal point i.e. 7.5.

Explanation:
To add the numbers 6.68 and 0.8, we will align the decimal points and add the digits in each place value.
Step 1: Align the decimal points:
6.68
0.80
-----
Step 2: Add the digits in each place value:
In the tenths place, we have 6 + 0 = 6.
In the hundredths place, we have 6 + 8 = 14.
Since 14 is greater than 10, we carry the 1 to the next place value and write down the remainder, which is 4.
In the thousandths place, we have 1 + 0 = 1.
In the ten thousandths place, we have 0 + 0 = 0.
Therefore, the sum of 6.68 and 0.8 is:
6.68
0.80
-----
7.48
Final Answer: The correct option is (b) 7.5.
