Answer:

Therefore, the number is -2.

Given:

The ratio of seven more than two times a number and five is equal to the ratio of nine and fifteen.

To find :

The ratio of seven more than two times a number and five is equal to the ratio of nine and fifteen. What is the number?

Solution :

(2x + 7) / 5 = 9 / 15

where x is the unknown number we want to find.

We can simplify this equation by cross-multiplying:

9(5) = 15(2x + 7)

45 = 30x + 105

Subtracting 105 from both sides, we get:

-60 = 30x

Dividing both sides by 30, we get:

x = -2

Therefore, the number is -2.
