Most generation and printing issues can be resolved with the checks below.
The generator shows an error
Check that all values are whole numbers and the minimum is no larger than the maximum. Seeds accept 1–40 letters, digits, hyphens or underscores. A very narrow range may not allow the selected regrouping mode. Mixed arithmetic needs a positive divisor. Widen the range or choose a preset, then generate again.
Settings changed but the sheet did not
Click Generate worksheet to apply number, question-count and seed changes. Paper-size changes affect layout only. Print buttons always use the current generated sheet. New random sheet changes the seed and applies the current settings.
Questions and answers do not seem to match
Check the worksheet identifier and seed at the bottom of both pages. Do not generate a new sheet between printing the questions and printing the key. Equivalent-fraction answers are the missing number; simplifying-fraction answers are complete fractions. Read the answer guide.
Printing or saving a PDF
Choose A4 or US Letter in both the tool and your browser print settings. Use portrait, 100% scale and disable browser headers/footers. Print questions and Print answer key select separate views. Download questions PDF and Download answer key PDF create separate files directly on your device. Browser Save as PDF remains an alternative. Read the printing guide.
Browser requirements
