How do you divide $306 into the ratio of 9:5:3? Can someone give me some advice on how to solve this problem?
GarryVolchara [31]
In order to divide $306 into the ratio of 9 to 5 to 3, first you have to make each section of the ratio represented by a variable, and put it into an equation.

9x + 5x + 3x = 306

Our next step is to simplify the left side of the equation by combining all of the like terms, the ones that contain variables.

17x = 306

Finally, to solve this equation, you have to divide both sides by 17 to isolate the variable x on the left side of the equation.

x = 18

However, this is not our answer as it isn't in a ratio format and doesn't really make sense. To find our ratio, we have to multiply each of our initial numbers (9, 5, and 3) by our variable, x.

9 * 18 = 162
5 * 18 = 90
3 * 18 = 54

You can verify that these numbers are correct because if you add them together you get 306.

Your final ratio is 162:90:54.

Hope this helps! :)

It takes you 4 hours to driving 180 miles .Explain how to use mental math to find your average speed .Then, Explain how your met
Doss [256]
To find your average speed, divide 180 by 4 which is 45.
Formula:
Plug the number into the equation
180 is d (distance)
4 is t (time
So it would be 180=r•4
1) get r by itself so divide 4 to both sides
2) 180/4 = r
3) 45 = r
