GPT-5 mini · Answer

Round to the nearest tenth: look at the hundredths digit (the second digit after the decimal). If it's 5 or more, round the tenths up; otherwise leave it.

A) 78.405 → hundredths = 0 → rounds to 78.4 (no)  
B) 79.4 → different whole number → 79.4 (no)  
C) 78.48 → hundredths = 8 → rounds to 78.5 (yes)  
D) 78.51 → hundredths = 1 → rounds to 78.5 (yes)  
E) 78.54 → hundredths = 4 → rounds to 78.5 (yes)
