To solve this question, we can look for the relationship between the numbers given and derive the answer for 115 based on this relationship.
First, we see that 80 and 100 have a specific ratio. To find the ratio of 80 to 100, we can write it as:
Ratio = 80 / 100 = 0.8
Next, we need to find the equivalent value for 115. We can set up a proportion to figure this out:
Let x be the equivalent value for 115.
Now we can set up the equation:
80 / 100 = 115 / x
To solve for x, we can cross-multiply:
80 * x = 100 * 115
Calculating the right side gives us:
80 * x = 11500
Now we can isolate x:
x = 11500 / 80
Doing the math:
x = 143.75
Therefore, if 80 corresponds to 100, then 115 corresponds to approximately 143.75. This means that within the same ratio, 115 scales up to about 143.75.
