Answer:
-15
Step-by-step explanation:
When adding together two negatives it works just as it would with positive numbers, just with the negative sign to properly negate it.
Step-by-step explanation:
For example:
Ex: 2:3 :: 6:9
In this question, the means are 3 and 6.
The extremes are 2 and 9.
We use this method to find whether the two ratios are equal or not.
We multiply the means and the extremes, and if there products are same, then these two ratios are proportional.
If these two ratios are proportional, their "means" = "extremes"
=> Means = Extremes
=> 3 x 6 = 2 x 9
=> 18 = 18
So, these two ratios are proportional.
Hope this helps you.

Step-by-step explanation:
So, the spot on the graph where they cross.
1/5 divided by 5/7 is 7/25

Your answer is 7/25
To find the decreased percentage,here's what we can do:
In this case,the eqaution would be:
