To find the percentage ratios of the aggregates between A and B reference curves, subtract the values of A from B, divide by A, and multiply by 100.
The question asks to find the percentage ratios of the aggregates between A and B reference curves. To do this, you can calculate the difference in the values of the aggregates for each curve, and then divide that difference by the value of aggregate A. Finally, multiply the result by 100 to get the percentage ratio.
Here is the step-by-step process:
Subtract the value of aggregate A for each curve from the value of aggregate B for the same curve.
Divide the difference by the value of aggregate A for the same curve.
Multiply the result by 100 to get the percentage ratio.
