To determine the number of Russian troops killed or wounded during World War I, we can follow these steps:
1. Identify the given data:
- Number of troops killed: [tex]\(1,700,000\)[/tex]
- Percentage of troops killed or wounded: [tex]\(55\% \)[/tex]
2. Convert the percentage to a decimal:
- [tex]\( 55\% = \frac{55}{100} = 0.55 \)[/tex]
3. Express the relationship between the number of troops killed and the total number of troops killed or wounded:
[tex]\[
\text{Number of troops killed} = \text{Number of troops killed or wounded} \times \text{Percentage killed or wounded}
\][/tex]
4. Let [tex]\( N \)[/tex] be the total number of troops killed or wounded. Then we have:
[tex]\[
1,700,000 = N \times 0.55
\][/tex]
5. To solve for [tex]\( N \)[/tex], isolate [tex]\( N \)[/tex] by dividing both sides of the equation by [tex]\( 0.55 \)[/tex]:
[tex]\[
N = \frac{1,700,000}{0.55}
\][/tex]
6. Perform the division:
[tex]\[
N = 3,090,909.090909091
\][/tex]
Therefore, approximately [tex]\( 3,090,909 \)[/tex] Russian troops were killed or wounded during the war.
The second part of the question pertains to the background of those who served in the war. Historically, most soldiers who served were from the peasant class.
Thus, the complete solution is:
According to the chart, [tex]$3,090,909$[/tex] of Russian troops were killed or wounded during the war. Most of those who served in the war were from the peasant class.
