question 14
order these runner times from fastest to slowest:
25.16, 25.3, 25.21, 25.09
○ 25.09, 25.16, 25.21, 25.3
○ 25.3, 25.21, 25.16, 25.09
○ 25.16, 25.09, 25.21, 25.3
○ 25.21, 25.09, 25.16, 25.3

Explanation:

Question 13

Step1: Recall fast time meaning

Faster time means a smaller number (less time taken).

Step2: Compare 25.3 and 25.16

Compare the two decimals: \( 25.16 < 25.3 \), so 25.16 is faster. Thus Minh is correct.

Step1: Recall fast time order

Faster time is smaller number. So order from smallest to largest (since smallest is fastest, largest is slowest).

Step2: Compare the decimals

Compare \( 25.09, 25.16, 25.21, 25.3 \). We know \( 25.09 < 25.16 < 25.21 < 25.3 \). So order from fastest (smallest) to slowest (largest) is 25.09, 25.16, 25.21, 25.3.

Answer:

Minh
