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:
One tenth is 1/10 = 0.1 and one hundredth is 1/100 = 0.01.
Ten hundredths make one tenth: 1/10 = 10/100.
A fraction with denominator 10 or 100 can be written as a decimal, and a decimal as a fraction.
Add tenths and hundredths by renaming tenths as hundredths: 3/10 + 4/100 = 34/100.
Compare decimals place by place; 0.3 = 0.30 is greater than 0.27.
