Here are the step-by-step solutions to the problems on your worksheet.
1. Population density of China
*
Formula: Population $\div$ Area
*
Calculation: $1,321,851,888 \div 5,795,162$
*
Result: $\approx 228.09$
*
Rounding: We usually round population density to the nearest whole person. So,
228.
2. Population density of the U.S.
*
Formula: Population $\div$ Area
*
Calculation: $301,139,947 \div 5,692,955$
*
Result: $\approx 52.89$
*
Rounding: Rounds up to
53.
3. Population density of Monaco
*
Formula: Population $\div$ Area
*
Calculation: $32,671 \div 1.2$
*
Result: $\approx 27,225.83$
*
Rounding: Rounds up to
27,226.
4. Population density of Canada
*
Formula: Population $\div$ Area
*
Calculation: $33,056,500 \div 3,854,085$
*
Result: $\approx 8.57$
*
Rounding: Rounds up to
9.
5. Highest and Lowest Density (from questions 1-4)
* Comparing the numbers we just found:
* China: 228
* U.S.: 53
* Monaco: 27,226
* Canada: 9
*
Highest: Monaco
*
Lowest: Canada
6. Largest and Smallest Land Area (from questions 1-4)
* Comparing the "Area" numbers given in the text:
* China: 5,795,162
* U.S.: 5,692,955
* Monaco: 1.2
* Canada: 3,854,085
*
Largest: China
*
Smallest: Monaco
7. Population density of Wyoming
*
Formula: Population $\div$ Area
*
Calculation: $493,782 \div 97,818$
*
Result: $\approx 5.04$
*
Rounding: Rounds down to
5.
8. Population density of Pennsylvania
*
Formula: Population $\div$ Area
*
Calculation: $12,281,054 \div 46,055$
*
Result: $\approx 266.66$
*
Rounding: Rounds up to
267.
9. Higher density: Pennsylvania or Wyoming?
* Pennsylvania is 267 people per square mile.
* Wyoming is 5 people per square mile.
*
Answer: Pennsylvania has the higher density.

Note for Questions 10 & 11:
These questions ask you to look at a map in your textbook (pages A10-A11). Since I cannot see your specific book, here are the standard answers based on general geography knowledge that your teacher likely expects:
10. Two countries with largest areas of high population density:
* Usually, these are
India and
China. (Sometimes Japan or parts of Europe like Germany are also accepted depending on the map's color key).
11. City in the U.S. with highest population density:
* On most population density maps, the darkest area representing the highest density is around
New York City.
