Determine if one, both, or neither of the following is a proportion. 168=?2412, 84=?126
To determine if these are proportions, we need to check if the ratios of the two numbers are equal.
For the first statement 168 = ?2412, we can divide both sides by 12 to get:
14 = ?201
Since the ratio of 14 to 201 is not equal to the given ratio of 168 to 2412, this is not a proportion.
For the second statement 84 = ?126, we can divide both sides by 42 to get:
2 = ?3
Since the ratio of 2 to 3 is equal to the given ratio of 84 to 126, this is a proportion.
To determine if a given pair of values is a proportion, we need to check if the ratio of the two values is equal.
Let's check each pair:
1) 168 = ? 2412
To determine if this is a proportion, we calculate the ratio of the two values:
Ratio = 168 / 2412 ≈ 0.0697
Since the ratio is not equal to 1, this pair is not a proportion.
2) 84 = ? 126
Again, we calculate the ratio of the two values:
Ratio = 84 / 126 ≈ 0.6667
Since the ratio is not equal to 1, this pair is also not a proportion.
In conclusion, neither of the given pairs is a proportion.
