You can type your answer as a fraction using the ‘forward slash’ key.
Example: For one quarter,, enter 1/4
-
(5/11, 10/22)
1 mark(s)Correct
Incorrect
Hint
The denominators are the same (both 11) so you can simply subtract the numerators.
Example: 3/7 – 1/7 = 2/7

9. Question
9
-
(81.08)
1 mark(s)Correct

Question 10 of 36
10. Question
10
-
(308)
1 mark(s)Correct
Incorrect
Hint
This is an equation, so if you do the same to both sides, it still balances. If you add 10 to both sides, then the 10 on the left ‘disappears’, (because 10 – 10 = 0) so you are left with the answer.

Hint
If you use column subtraction then write 10 as 10.0 so you can align the columns. Another way to solve this is to take 6 from 10 and then add back 0.6 (because you were only asked to take 5.4 from 10).

Question 24 of 36

24
You can type your answer as a fraction using the ‘forward slash’ key.
Example: For one quarter,, enter 1/4
-
(7/10, 0.7, 14/20)
1 mark(s)Correct
Incorrect
Hint
The denominators are different so you can’t just add the numerators.
One way to find a common denominator is to multiply the two denominators together. Example: 1/3 + 1/4. If you multiply the denominators you get 12. Next you multiply the numerators by the right amounts. One-third equals four-twelfths, and one-quarter equals three-twelfths. Now you can add these numerators, to get 4/12 + 3/12 = 7/12.
