Can someone give me an example on how to solve a proportion.
6 e
-- = --
25 80
10 x
-- = --
20 30
you need mutiply 10x30 and then you need to divde by 20 to get the value of x
thanks for the help
To solve a proportion, you need to find the missing value that makes the two ratios equal. In this example, we have:
6 / 25 = e / 80
To find the value of 'e', we can cross-multiply. Cross-multiplication means multiplying the numerator of the first fraction by the denominator of the second fraction, and vice versa. Let's do that:
6 * 80 = 25 * e
Now, we have:
480 = 25e
To isolate 'e', we need to get rid of the coefficient of 'e', which is 25. We can do this by dividing both sides of the equation by 25:
480 / 25 = e
The result is:
e = 19.2
So, the value of 'e' that makes the two ratios equal is 19.2.
