How does this quiz work?

Read each question, choose one answer among A, B, C and D, then check it: a short explanation appears after every answer. Your score out of 10 is shown at the end, and you can restart the quiz as often as you like.

What should you review before the quiz?

Reread the key facts of the lesson and the worked example. If a question is hard, go back to the matching part of the lesson, then try the quiz again. Write your work on scrap paper: most mistakes come from skipping a step, not from the idea itself.

Remember:

Only fractions with the same denominator can be added or subtracted directly.
A common denominator is a multiple of both denominators, and the smallest one is the least common denominator.
Renaming a fraction multiplies its numerator and denominator by the same number.
When subtracting mixed numbers, regroup one whole if the first fraction is smaller.
Benchmarks 0, 1/2 and 1 give a quick estimate to check an answer.
