Angles
A right angle measures how many degrees?
90°
What is 1/2 + 1/4?
3/4
Lily has 12 apples. She gives 4 to her friend. How many apples does she have left?
8
What is the 4th term in the sequence: 3, 6, 9, 12, ...?
12 (The pattern is adding 3 each time)
What is the probability of flipping a fair coin and getting heads?
1/2
If one angle in a triangle is 90° and another is 45°, what is the measure of the third angle?

A bus has 40 seats. If 75% of them are occupied, how many seats are taken?
30 seats (40 × 0.75 = 30)
If the nth term of a sequence is given by 4n - 2, what is the 5th term?
18 (4(5) - 2 = 18)
A bag contains 3 red, 4 blue, and 5 green balls. What is the probability of drawing a blue ball?
4/12 or 1/3
A straight line is divided into two angles. If one angle is 65°, what is the other angle?
115° (since a straight line is 180° → 180° - 65° = 115°)
Convert 3 1/5 into an improper fraction.

A farmer has 3 fields. Each field has 15 rows of crops, and each row contains 10 plants. How many plants does he have in total?
450 plants (3 × 15 × 10 = 450)
A sequence follows the rule: multiply the previous term by 2. If the first term is 3, what is the 4th term?
24 (3 → 6 → 12 → 24)
A number is chosen randomly from 1 to 10. What is the probability that it is a multiple of 3?
3/10 (Multiples of 3: {3, 6, 9} → 3 out of 10)
A quadrilateral has angles measuring 90°, 80°, and 95°. What is the measure of the fourth angle?
95° (since the sum of angles in a quadrilateral is 360° → 360° - (90° + 80° + 95°) = 95°)
Multiply 5/6 by 3/4 and simplify your answer.
5/8
If a car travels 90 km in 1.5 hours, what is its speed in km per hour?
60 km/h (90 ÷ 1.5 = 60)
A pattern starts at 20 and follows the rule "subtract 3 each time." What is the 6th term?
5 (20 → 17 → 14 → 11 → 8 → 5)
A spinner is divided into 8 equal sections numbered 1-8. What is the probability of spinning a prime number?
3/8 (Prime numbers: {2, 3, 5, 7} → 4 out of 8)
Two parallel lines are cut by a transversal. If one alternate interior angle is 72°, what is the measure of the corresponding alternate interior angle on the opposite side?
72° (alternate interior angles are equal)
Divide 2 2/3 by 5/8 and simplify the answer.
4 4/5 (Convert 2 2/3 to 8/3, then multiply by 8/5)
A store is having a 20% discount sale. If an item originally costs $75, what is the new price after the discount?
$60 (20% of 75 = 15 → 75 - 15 = 60)
If the nth term of a sequence is given by 2n² - 5n + 3, what is the 7th term?
59 (2(7²) - 5(7) + 3 = 98 - 35 + 3 = 59)
A class has 12 boys and 18 girls. If one student is chosen at random, what is the probability that it is a girl?
18/30 or 3/5
