2

If Sara is 10 years old, and her brother is half her age, we can determine his age by dividing Sara's age by 2.

Sara's brother's age = Sara's age / 2

Sara's brother's age = 10 / 2

Sara's brother's age = 5

Therefore, Sara's brother is 5 years old.

Explanation

If Sara is 10 years old, and her brother is half her age, we can determine his age by dividing Sara's age by 2.

Sara's brother's age = Sara's age / 2

Sara's brother's age = 10 / 2

Sara's brother's age = 5

Therefore, Sara's brother is 5 years old.

11. Which of the following is not divisible by 3?

6

9

15

25

In order to determine if a number is divisible by 3, we can check if the sum of its digits is divisible by 3. If the sum is divisible by 3, then the number itself is divisible by 3. However, if the sum is not divisible by 3, then the number is also not divisible by 3. In this case, the number 25 has a sum of digits equal to 7, which is not divisible by 3. Therefore, 25 is not divisible by 3.

Explanation

In order to determine if a number is divisible by 3, we can check if the sum of its digits is divisible by 3. If the sum is divisible by 3, then the number itself is divisible by 3. However, if the sum is not divisible by 3, then the number is also not divisible by 3. In this case, the number 25 has a sum of digits equal to 7, which is not divisible by 3. Therefore, 25 is not divisible by 3.

12. Which of the following is not completely divisible by 4?

16

24

30

32

All the given numbers are divisible by 4 except for 30. When a number is divisible by 4, the last two digits of the number must be divisible by 4. In the case of 30, the last two digits are 30, which is not divisible by 4. Therefore, 30 is not completely divisible by 4.

Explanation

All the given numbers are divisible by 4 except for 30. When a number is divisible by 4, the last two digits of the number must be divisible by 4. In the case of 30, the last two digits are 30, which is not divisible by 4. Therefore, 30 is not completely divisible by 4.

13. Which adds up to 12?

6+6

5+7

10+2

All of the above

All three equations add up to 12:
6 + 6 = 12,
5 + 7 = 12,
10 + 2 = 12.
Therefore, the correct answer is "All of the above."

Explanation

All three equations add up to 12:
6 + 6 = 12,
5 + 7 = 12,
10 + 2 = 12.
Therefore, the correct answer is "All of the above."

14. Which answer choice produces a value that is bigger than 70?

50 + 20

71 - 3

98 - 21

33 x 2

The equation 98 - 21 produces a result of 77, which is greater than 70. By subtracting 21 from 98, we find that the value exceeds 70. In comparison, the other choices either produce values equal to or smaller than 70, making this the only option where the result is larger than 70. Thus, 98 - 21 is the correct answer.

Explanation

The equation 98 - 21 produces a result of 77, which is greater than 70. By subtracting 21 from 98, we find that the value exceeds 70.
