A fresh set for the next session
Practice again.
With different numbers.
Choose a calculation type and units, then create 6, 12 or 18 original questions. A repeat code gives you the same set with the same options. Download the student sheet and worked key separately.
Build your set
Use 1–16 letters or numbers. The code contains no saved progress. Changing any option clears the current preview.
Choose options and build a worksheet.
Student worksheet
Round final answers to 3 decimal places when needed. Allow space to show your work. The downloaded student file contains questions and working space only.
Separate worked key
Check units and intermediate steps after attempting the questions. Viewing the key does not mark any practice drill solved.
Open, print and keep
Each HTML file opens offline, with no scripts or external resources. Use the selected paper size at 100% scale and turn off browser print headers/footers. Student sheets use six questions per page; worked keys use three.
Follow the units
US liquid gallons use the exact 3.785411784-liter definition. Cubic-foot conversions derive from 12 inches per foot and 231 cubic inches per US gallon. Rates are constant or average over the stated interval; a day is a fixed 24-hour duration. Calculations retain unrounded factors; printed final answers use three decimal places.

These questions are original arithmetic practice, not official exam questions, approved training or operational instructions. The selected-exercise worksheet and interactive calculator and drills remain available.
