Question: The ratio of boys to girls in a math class is 5:8. How many girls are in the class if the total number of students in the class is 260?
Answer: If the ratio of boys to girls in the math class is 5:8, the total ratio of the number of boys and girls in the math class is 5 + 8 = 13. The fraction that represents the number of boys in the class is 5 / 13, and since there are 260 students in the class, the number of boys in the class is 5 / 13 * 260 = 100. The number of girls in the class is 260 - 100 = 160. The answer is 160.

Question: Mica went to the grocery store and bought 2 kilograms of pasta that costs $1.5; 1/4 kilogram of ground beef costs $8 for 1 kilogram; two jars of pasta sauce costs $2 per jar. Mica also wants to buy a $6 Quesadilla for snacks. How much money should she have with her to buy all those?
Answer: Two kilograms of pasta cost $1.5 x 2 = $3. One - fourth kilogram of ground beef cost $8 x 1 / 4 = $2. Two jars of pasta sauce cost $2 x 2 = $4. The total cost for the pasta, beef, and sauce is $3 + $2 + $4 = $9. Since Mica also wants to buy Quesadilla, she should have $9 + $6 = $15. The answer is 15.

Question: A church has 120 members. 40% are adults. The rest are children. How many children more children are there than adults?
