What percentage of the world export commodities in figure 1 is represented by crude oil?

From the given figure 1, we can see that the crude oil export is represented by the blue-colored bar. To calculate the percentage of the world export commodities represented by crude oil, we need to find the total export value of all the commodities and then find the proportion of the export value represented by crude oil. The total export value of all commodities is the sum of the values of all the bars in the graph. Adding up the values of all the bars, we get: 20.8 + 18.7 + 11.2 + 7.8 + 6.3 + 5.3 + 3.3 + 2.6 + 2.3 + 1.7 = 80.0 Therefore, the total export value of all commodities is 80.0. Now, to find the percentage of the world export commodities represented by crude oil, we need to divide the value of crude oil export (18.7) by the total export value of all commodities (80.0) and then multiply the result by 100. Percentage of crude oil export = (18.7/80.0) x 100 = 23.375 Therefore, the percentage of the world export commodities represented by crude oil is approximately 23.4%. The closest option is 23.74%, which is the correct answer.
