i like how nobody answered
SASUKEEEEEEEEE
The answer is D did a USATestPrep on it 👌
To determine which two ratios form a proportion, we need to check if they are equivalent ratios.
To do this, we can cross multiply the terms of the ratios.
Let's go through each option:
A) 1 : 2 and 4 : 2
Cross multiplying gives us: 1 * 2 = 4 * 2
2 = 8
Since 2 does not equal 8, option A does not form a proportion.
B) 1 : 2 and 6 : 3
Cross multiplying gives us: 1 * 3 = 6 * 2
3 = 12
Since 3 does not equal 12, option B does not form a proportion.
C) 2 : 1 and 2 : 4
Cross multiplying gives us: 2 * 4 = 2 * 1
8 = 2
Since 8 does not equal 2, option C does not form a proportion.
D) 2 : 1 and 6 : 3
Cross multiplying gives us: 2 * 3 = 6 * 1
6 = 6
Since 6 equals 6, option D forms a proportion.
Therefore, the correct answer is option D) 2 : 1 and 6 : 3.
