how do i solve proportions??? please help!! And how do i kno what corrisponding sides are???
To solve a proportion, use cross products.
For example, the proportion = can be solved as follows:
= Write the original proportion.
50 n = 3 180 Find the cross products.
50n = 540 Multiply.
= Divide both sides by 50 to find n.
n = 10.8 Simplify.
for corrisponding sides they are proportinal like a triangle sides are 2,4 and 2 and the bigger one 4,8, and 4 you know they're proportinial because the first ones are divisable just like the second and third.

I wrote something out on paint so that I could explain it better.
Just go to tiny pic dot c0m
and after the c0m write:

To solve proportions, you can use cross products. Here's an example:
Let's say you have the proportion: 2/3 = x/9
To solve for x, you can use cross products:
3 * x = 2 * 9
3x = 18
To isolate x, divide both sides of the equation by 3:
x = 18/3
x = 6
So the value of x in this proportion is 6.
As for corresponding sides, in a proportion, corresponding sides are the sides that are in the same position in two different ratios. For example, in a triangle, if you have one side length ratio of 2:4:2 and another ratio of 4:8:4, the corresponding sides are the ones that are in the same position, such as the first side in the first ratio corresponding to the first side in the second ratio.
You can determine if the corresponding sides are proportional by checking if they have the same ratio or if they are divisible by the same number. In this case, the first sides are both 2 and 4, and they are divisible by the same number (2). So, the corresponding sides in this example are proportional.
I hope this explanation helps! Let me know if you have any further questions.
