Question

Accepted Answer

From the bar graph, the investment in 2018 is approximately 65 million dollars and in 2015 is approximately 60 million dollars. To find the ratio of investment in 2018 to that in 2015:

- Investment in 2018 = 65 million dollars  
- Investment in 2015 = 60 million dollars

Now, simplify the ratio 65 : 60.  
Divide both numbers by their greatest common divisor (5):

$$
\frac{65}{5} : \frac{60}{5} = 13 : 12
$$

Therefore, the ratio of investment in 2018 to that in 2015 is **13 : 12**.
