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:
A fraction names equal parts of a whole, so the parts must all be the same size.
The denominator is the number of equal parts in the whole; the numerator is the number of parts counted.
A unit fraction \(\frac{1}{b}\) names one equal part of a whole cut into \(b\) parts.
The fraction \(\frac{a}{b}\) is \(a\) parts, each of size \(\frac{1}{b}\).
On a number line from 0 to 1, \(\frac{a}{b}\) is the point reached after \(a\) steps of length \(\frac{1}{b}\).
