Question

Joe does 25 sit ups each day. How many set ups does he do in three weeks? Remember, one week has seven days.

Answer 1

525 sit-ups

Step-by-step explanatiSince there are 7 days in a week, and there are 3 weeks, you can multiply 7 * 3 = 21 to find out how many days Joe is doing situps. Next, you need to multiply the number of situps per day by the number of days: 25 * 21 = 525. Joe will do 525 situps in 3 weeks.

Hope this helps! :)
