Question: Rose had 10 kilograms of rice. She cooked 9/10 kilograms in the morning and 1/4 of the remaining in the evening. How many grams of rice did she have left?
Answer: Rose cooked 10 x 9 / 10 = 9 kilograms of rice in the morning. She had 10 - 9 = 1 kilogram of rice left then. One kilogram is equal to 1 x 1000 = 1000 grams. So, Rose cooked 1000 x 1 / 4 = 250 grams of rice in the evening. Therefore, she has 1000 - 250 = 750 grams of rice left. The answer is 750.

Question: Ashley had a birthday party and invited 20 of her friends, telling them to each invite one more person to attend the party. If half the number of the invited guests each came with one more person, what's the total number of people at the party, including Ashley?
Answer: If she invited 20 friends, then the number of friends who came with one more person is 1 / 2 * 20 = 10. If the 10 friends came with 10 more people, the total number of guests becomes 20 + 10 = 30 guests. If you add Ashley, the total number of people in the party is 30 + 1 = 31 people. The answer is 31.

Question: On a road map, 1/4 inch represents 8 miles of actual road distance. The towns of Pence and Hillcrest are represented by points 3 3/8 inches apart on the map. What is the actual distance, in miles, between the towns?
Answer: If 1 / 4 inch on the map represents 8 miles on real land, 1 inch represents 4 * 8 = 32 miles. Since 1 inch represents 32 miles, 3 inches represent 3 * 32 = 96 miles. 1 / 4 inch represents 8 miles, 1 / 8 inch represents 8 / 2 = 4 miles because 1 / 8 is half of 1 / 4. If 1 / 8 inch represents 4 miles, 3 / 8 of an inch represents 3 * 4 = 12 miles. This means 3 3 / 8 inches on the map translate to 96 + 12 = 108 miles. The answer is 108.
