Proportional Relationships Quick Check Determine if 2.5/10 = 12/48 or 2.5/2 = 12/24 is a proportion(1 point)
To determine if a pair of ratios is a proportion, we need to check if they are equal to each other.
In the first pair 2.5/10 = 12/48:
2.5/10 is equal to 0.25
12/48 is equal to 0.25
Since both ratios are equal to 0.25, the first pair is a proportion.
In the second pair 2.5/2 = 12/24:
2.5/2 is equal to 1.25
12/24 is equal to 0.5
Since 1.25 is not equal to 0.5, the second pair is not a proportion.
Therefore, the pair 2.5/10 = 12/48 is a proportion.
