Final answer:
To determine which statement is true, compare the fractions in each statement and determine if they are greater or less than each other.
Step-by-step explanation:
To determine which statement is true, we can compare the fractions and see which one is greater or less than the other. Let's analyze each statement:
A. 29/35 = 0.8286 and 20/30 = 0.6667. So, 29/35 > 20/30 is true.
B. 18/34 = 0.5294 and 16/32 = 0.5. So, 18/34 > 16/32 is false.
C. 14/21 = 0.6667 and 17/24 = 0.7083. So, 14/21 > 17/24 is false.
D. 20/15 = 1.3333 and 28/23 = 1.2174. So, 20/15 > 28/23 is true.
Based on our analysis, statement A and statement D are true.
