Question

which line of code will display the variable num rounded to the nearest tenth?
a. print(num, round)
b. print(round(num, 1))
c. print(num rounded)
d. print(round(num, 1))

Explanation:

To round a number to the nearest tenth, we use the round() function in Python, where the second argument is the number of decimal places (1 for tenths). Let's analyze each option:

• Option A: print(num, round) will print the number and the round function object, not the rounded number.
• Option B: print(round(num, 1)) correctly uses the round function with num as the number and 1 as the decimal place (tenth), so it will print the number rounded to the nearest tenth.
• Option C: print(num rounded) is invalid syntax in Python.
• Option D: print(round(num, 1)) (assuming a typo in the original, but the correct syntax for rounding to tenth is round(num, 1), and this option (if the typo is corrected) is the same as B. But from the given options, B is the correct one with proper syntax.

Answer:

B. print(round(num, 1))
