Question

Find the missing number in the proportion.
25 5
_____=_____
x+5 6

Answer 1

To find the missing number in the proportion, we can use cross multiplication.

25/(x+5) = 5/6

First of all, we cross multiply:

25 * 6 = 5 * (x+5)

150 = 5x + 25

Next, we can isolate the x term:

5x = 150 - 25

5x = 125

Finally, we divide both sides by 5 to solve for x:

x = 125/5

x = 25

So, the missing number in the proportion is 25.
