Question 1
Why is 231 not divisible by 6?
- It is divisible by 3 but not by 2
- It is divisible by 2 but not by 3
- It ends in 1, so it is a prime number
It is divisible by 3 but not by 2
Hint: 231 is odd, so 2 does not go into it. A number divisible by 6 needs both 2 and 3.
Question 2
What is 3 + (-18)?
3 + (-18) = ?
- 21
- -15
- -21
- 15
-15
Hint: Different signs: subtract the sizes, 18 − 3 = 15. Keep the sign of -18, the number farther from zero. The answer is -15.
Question 3
What is 18.63 + 11.4?
18.63 + 11.4 = ?
answer box
30.03
Hint: Line up the decimal points and give every number two decimal places: 18.63 + 11.40. Add column by column: 30.03.
Question 4
What is 1/8 × 1/2?
1/8 × 1/2
- 1/10
- 1/16
- 1/5
1/16
Hint: Multiply the numerators. Multiply the denominators. Then simplify.
Question 5
Which is the greatest?
- 1 1/2
- 0.45
- 2/5
- 1.75
1.75
Hint: Change the fractions to decimals (1/4 = 0.25, 1/2 = 0.5, 3/4 = 0.75) so you can compare them.
Question 6
What percent of the bar is shaded?
answer box%
50 %
Hint: 2 of the 4 equal parts are shaded: 2/4. 2/4 = 50/100 = 0.5 = 50%.
Question 7
Two stores sell the same scooter. Which store has the lower sale price?
Store Regular price Sale A $90.00 25% off B $120.00 10% off - Store B
- They cost the same
- Store A
Store A
Hint: Store A: pay 75% of $90.00 = $67.50. Store B: pay 90% of $120.00 = $108.00. Store A is cheaper.
Question 8
What is the value of 2(a + 3) when a = 5?
- 16
- 13
- 11
- 10
16
Hint: Do the brackets first: 5 + 3 = 8. Then 2 × 8.
Question 9
Which expression gives the value for any term number n?
n 1 2 3 4 value 8 11 14 17 - n + 8
- 3n + 5
- 3n + 8
- -3n + 5
3n + 5
Hint: The value changes by 3 each time n goes up by 1, so the rule starts with 3n. At n = 1, 3n is 3 but the table shows 8, so add 5: 3n + 5.
Question 10
Which equation matches this sentence? "Nine times a number, plus 7, equals 25."
- 9(n + 7) = 25
- 9n − 7 = 25
- 7n + 9 = 25
- 9n + 7 = 25
9n + 7 = 25
Hint: "Nine times a number" is 9n. "Plus 7" adds 7 after multiplying: 9n + 7. "Equals 25" finishes it: 9n + 7 = 25.
