Question: On each of 7 Mondays, it rained 1.5 centimeters. On each of 9 Tuesdays it rained 2.5 centimeters. How many more centimeters did it rain on Tuesdays than Mondays?
Answer with step-by-step thinking: Mondays: 7 * 1.5 = 10.5. Tuesdays: 9 * 2.5 = 22.5. 22.5 - 10.5 = 12 cm. It rained 12 centimeters more on Tuesdays than on Mondays.
So the answer is 12.


Question: Georgia is working on a math test with 75 problems on it. After 20 minutes she has completed 10 problems. After another 20 minutes, she has completed twice as many problems. She has 40 minutes to complete the rest of the test. How many problems does she have left to solve?
Answer with step-by-step thinking: Georgia's test started with 75 problems and then Georgia completed 10, 75 - 10 = 65 problems. After 20 minutes she completes twice as many problems, 10 x 2 = 20. With 40 minutes left she has completed 10 + 20 problems = 30 problems. From the original 75 problems she has solved 30, 75 - 30 = 45 problems she has left.
So the answer is 45.


Question: James and Lisa ordered 2 small pizzas. Each pizza has 6 slices. James ate 2/3 of all the slices. How many slices of pizza did James eat?
Answer with step-by-step thinking:
