The kind of problems you'll get

Choose the model that shows the same amount as the reference, using the same whole.

  1. Write 2/3 in sixths.

    Answer: 2/3 = 4/6. Multiply both parts by 2.

Most problems on this sheet sit beside a picture, model or diagram, so this is the worked example the sheet itself prints. The answer key on page two prints the answer under every problem.

Every print pulls a fresh set of problems at this level, so a make-up test or a second sibling never gets the same sheet.

What's on each sheet

Every version prints on US Letter or A4, with its answer key after the problems.

This sheet is one of the versions on the 4th grade equivalent fractions page, with its own difficulty choices and its own answer key.

How to teach this

Ask "what did the bottom get multiplied by?" before anything else, and have your child write that little × 4 next to the equals sign so the step stays visible. Check a finished answer by simplifying it back: 12/20 should return to 3/5. If your child is guessing, cover the second denominator and let them build the new fraction themselves.

Watch for: Kids add the same number to the top and bottom, turning 1/2 into 2/3. Adding changes the fraction's size; only multiplying both parts keeps it. Kids multiply the bottom and copy the top across unchanged. Whatever the denominator was multiplied by, the numerator gets the same.
