Which decimal is the largest among 0.8, 0.75, 0.72, and 0.77?

• A. 0.8
• B. 0.75
• C. 0.72
• D. 0.77

Answer: (A)

When comparing decimals, the first place after the decimal matters most. Look at the tenths digits of these numbers: 0.8 has 8 tenths, while the others each have 7 tenths (0.75, 0.72, and 0.77). Since 8 is larger than 7, 0.8 is bigger than all of them. Even though 0.8 can be written as 0.80, its tenths place is still 8, which keeps it larger than the others. So the largest decimal is 0.8.
