Here's an example:
'On each biscuit (was wrote) (wrote) (write) (was written) (was writ) a word in bright pink icing.'
For this type of question you will need to circle the correct word(s) that are shown here in brackets that will ensure the sentence makes sense.
Here you can see that you need to be thinking about the sentence in past tense (on the paper there will be an entire passage that will help you to choose which tense you think the narrator is writing in).
The correct form of past tense for this question is '(was written)'. This is the past tense form of 'write' and works with the singular object.
Something to watch out for on these multiple choice questions is that the lettering of each answer may not always be in alphabetical order i.e. ABCD, sometimes they switch them around so that the 3rd answer may indeed be A and not C. Be super careful when transferring answers onto your answer sheet as you could easily lose marks even when you knew the correct answer.

The key to this question is knowing your maths termionoly, once you've got that, this question will make a lot more sense.
Perimetre essentially means the lengths of each side of the shape added together.
Regular means that each of the sides is the same length.
Therefore a shape with 9 sides, each measuring 4cm requires this sum:
9 x 4 = 36
Therefore the answer to the question is 36cm

So in order to compare the size of fractions they need to have the same denominator (bottom number). You can do this by picking a number that you can easily multiply the fractions into, for example 20.
To get the bottom number of 3/10 to 20 you need to multiply both the top and bottom number by 2. 3 x 2 = 6, so you get 6/20
To get the bottom number of 2/5 to 20 you need to multiply both the top and bottom number by 4. 2 x 4 = 8, so you get 8/20
To get the bottom number of 1/2 to 20 you need to multiply both the top and bottom number by 10. 1 x 10 = 10, so you get 10/20
9/20 already has the correct denominator, so you don't need to change anything.
You can now compare the top numbers (numerators) to place them in order:
6/20, 8/20, 9/20, 10/20
Don't forget to convert them back to the original fractions
3/10, 2/5, 9/20, 1/2

To start, find out 10 per cent of 150. To find a percent, divide by 100 and multiply by the percent. 150 divided by 100 is 1.5, 1.5 multiplied by 10 is 15. Finally, add the 10% on to the original, so 150 + 15 = 165cm. Alternatively, to find 10%, divide by 10, and continue to add to the original.

40/100 can be simplified to 2/5. If we times 2/5 by 150, we know that 5 goes into 150, 30 times. Now we simply times 30 by the numerator (2). 30 x 2 = 60.
Ans: 60

1st step: Find a common bottom number (denominator)
The easiest way is to multiply both top and bottom of each fraction, by the bottom number of the opposite fraction:
1st fraction: 5 x 8 = 40, 7 x 8 = 56, so we get a fraction 40/56
2nd fraction: 2 x 7 = 14, 8 x 7 = 56, so we get a fraction 14/56
2nd step: Now we have the same bottom number, we can simply subtract the two top numbers (numerators)
40/56 - 14/56 = 26/56
Step 3: Simplify or make the number smaller by finding a common factor
Since both 26 and 56 are divisible by 2, then we get: 26/2 = 13, 56/2 = 28
So our final answer is 13/28.
