✍️ Sample IAAT Questions & Answers
1. In a class of 50 students, 23 are girls and the remaining are boys. Find the ratio of the number of boys to the number of girls.
Explanation: Total number of students = 50; Number of girls = 23. Total number of boys = Total number of students - Total number of girls = 50 - 23 = 27 Therefore, the desired ratio is, (Number of boys: Number of girls), which is 27:23.
2. A batch of paint requires blue and yellow in a 3:1 ratio. To make 40 gallons of this paint, how many gallons of yellow are needed?
Total parts = 3 + 1 = 4; yellow = (1/4) × 40 = 10 gallons.
3. Sophia baked cookies for her class. Every student had one cookie, including Sophia. At the end of the school day, 3 cookies were left. How many kids were in the class?
Explanation: Let's denote the total number of cookies Sophia baked as 𝑛. Since every student, including Sophia, had one cookie, and 3 cookies were left at the end of the school day, the number of cookies eaten was n − 3. This number of cookies eaten is equal to the number of kids in the class since each student had one cookie. Therefore, the number of kids in the class is represented by the expression 𝑛 − 3.
4. Which of the following lists of numbers is ordered from greatest to least?
To compare the numbers, convert them all to the same format. -3/2 is equal to -1.5. So the numbers are -1.5, -1.5, 0, and 0.5. When ordered from greatest to least, the sequence is 0.5, 0, and then -1.5. Since -3/2 and -1.5 are equal, their order doesn't matter relative to each other. The correct list is 0.5, 0, -3/2, -1.5.
5. Which of the following expressions represents the sum of 5 and twice x?
Explanation: The sum of 5 and twice x is represented by the expression x + 5, as "twice x" is equivalent to 2x, and the sum of 5 and 2x is x + 5.
6. If 12 workers can complete a job in 8 days, how many days will 6 workers need to complete the same job?
This is inverse proportion: 12 × 8 = 6 × d, so d = 96 ÷ 6 = 16 days.
