About how many casualties did the major countries suffer during the war?
A. 7 million
B. 13 million
C. 17 million
D. 25 million
Answer (2)
Identify the number of casualties for each major country.
Sum the casualties: 3 , 190 , 235 + 7 , 142 , 558 + 6 , 160 , 800 + 323 , 018 = 16 , 816 , 611 .
Round the sum to the nearest million: 16 , 816 , 611 ≈ 17 , 000 , 000 .
The approximate number of casualties is 17 million .
Explanation
Understanding the Problem We are given a table of military casualties from World War I for Great Britain, Germany, France, and the United States. The question asks us to estimate the total number of casualties suffered by these major countries. To do this, we need to add up the 'All Casualties' for each country and then round to the nearest million.
Identifying Casualties First, we identify the 'All Casualties' for each country:
Great Britain: 3,190,235
Germany: 7,142,558
France: 6,160,800
United States: 323,018
Calculating Total Casualties Next, we sum these values to find the total number of casualties: 3 , 190 , 235 + 7 , 142 , 558 + 6 , 160 , 800 + 323 , 018 = 16 , 816 , 611
Rounding to Nearest Million Now, we round the total to the nearest million. Since 16,816,611 is closer to 17,000,000 than to 16,000,000, we round up to 17 million.
Final Answer Therefore, the major countries suffered approximately 17 million casualties during World War I.
Examples
Understanding the scale of casualties in historical events like World War I helps us appreciate the impact of such conflicts. In real life, estimating large numbers is useful in many fields, such as economics, where we might estimate a country's total debt, or in environmental science, where we might estimate the total amount of pollution produced by various sources. These estimations help us grasp the magnitude of the issues and make informed decisions.
The major countries suffered approximately 17 million casualties during World War I. This estimate is obtained by summing the total casualties from Great Britain, Germany, France, and the United States and rounding to the nearest million. The final calculated total is 16,816,611, which rounds to 17 million.
