1. 1.A movie starts at 2:45 PM and lasts for 1 hour and 30 minutes. What time does it finish?

   • A3:15 PM
   • B4:00 PM
   • C4:15 PM
   • D4:30 PM
   Show answer and working

   Answer: C (4:15 PM)

   Add the hour first, then the minutes. 2:45 PM plus 1 hour is 3:45 PM. Adding 15 minutes reaches 4:00 PM, and the remaining 15 minutes takes you to 4:15 PM. Splitting the 30 minutes at the o'clock helps you avoid writing 3:75. The answer 3:15 PM only adds the 30 minutes and forgets the hour.

2. 2.What is the value of the digit 5 in 52?

   • A5
   • B50
   • C500
   • D2
   Show answer and working

   Answer: B (50)

   The value of a digit depends on its place. In 52, the 2 is in the ones place and the 5 is in the tens place, so it stands for 5 tens, which is 50. The answer 5 gives the digit itself, not its value. If the number were 523, the 5 would be in the hundreds place and be worth 500.

3. 3.Which is larger: 1/2 or 1/4?

   • A1/2
   • B1/4
   • CThey are equal
   • DNone
   Show answer and working

   Answer: A (1/2)

   When two fractions both have 1 on top, the one with the smaller bottom number is bigger, because the whole is cut into fewer, larger pieces. 1/2 means one of two equal pieces, and 1/4 means one of four smaller pieces. Picture a pizza: half the pizza is more than a quarter. So 1/2 is larger.

4. 4.How many sides does a pentagon have?

   • A4
   • B5
   • C6
   • D8
   Show answer and working

   Answer: B (5)

   The word 'pentagon' starts with 'penta', which means five, so a pentagon has five sides and five corners. Linking shape names to their number prefixes helps: a triangle has 3 sides, a quadrilateral has 4, a hexagon has 6 and an octagon has 8, just as an octopus has eight arms.

5. 5.What time is it if the big hand is on 12 and the little hand is on 6?

   • A12:00
   • B12:30
   • C6:00
   • D6:30
   Show answer and working

   Answer: C (6:00)

   On an analogue clock, the big (minute) hand on 12 means it is exactly o'clock. The little (hour) hand points to the hour, which is 6, so the time is 6:00. A common mistake is reading the big hand as the hour, which gives 12:00 or 12:30. 6:30 would have the big hand on the 6.

6. 6.Convert 100cm to meters.

   • A1m
   • B10m
   • C100m
   • D0.1m
   Show answer and working

   Answer: A (1m)

   There are 100 centimetres in 1 metre. So 100 cm is exactly 1 m. To change centimetres into metres, divide by 100: 100 ÷ 100 = 1. A metre is about the height of a kitchen bench. The answer 100 m would be the length of a running track straight, which is far too long.

7. 7.If a toy costs $2 and you have $5, how much change do you get?

   • A$1
   • B$2
   • C$3
   • D$4
   Show answer and working

   Answer: C ($3)

   Change is the money you get back when you pay more than the price. Subtract the cost from the money you hand over: $5 − $2 = $3. You can check by counting on from the price: $2 plus $1 is $3, $4, $5, which is three more dollars. The answer $2 confuses the price with the change.

8. 8.What is 12 divided by 3?

   • A3
   • B4
   • C5
   • D6
   Show answer and working

   Answer: B (4)

   Dividing 12 by 3 means sharing 12 into 3 equal groups, or asking how many 3s make 12. Count by threes: 3, 6, 9, 12. That is four threes, so 12 ÷ 3 = 4. You can check with the matching multiplication fact: 3 × 4 = 12. The answer 3 is the number you divided by.

9. 9.What is the next number: 10, 12, 14, __?

   • A15
   • B16
   • C17
   • D18
   Show answer and working

   Answer: B (16)

   Find the rule by looking at the gap between numbers: 10 to 12 is +2, 12 to 14 is +2. So the pattern adds 2 each time, and the next number is 14 + 2 = 16. These are even numbers counting up by twos. The answer 15 only adds 1 and breaks the pattern.

10. 10.How many grams in a kilogram?

    • A10
    • B100
    • C1000
    • D10000
    Show answer and working

    Answer: C (1000)

    The prefix 'kilo' means one thousand, so a kilogram is 1000 grams, just as a kilometre is 1000 metres. A one-litre bottle of water has a mass of about 1 kilogram. Remembering that 'kilo' means 1000 helps with many metric conversions. The answer 100 confuses kilograms with centimetres in a metre.
