Let's go through the math problems from the image:

7. Pattern Rule

Rule: Add 4
First item: 6

• Start with 6, then add 4 repeatedly.
• Numbers: 6, 10, 14, 18, 22.
  • The correct option is A (10, 14, 18, 22).

8. Rounding

Round 84,324 to the nearest thousand:

• The hundreds digit is 3, so round down to 84,000.
  • The correct option is D (84,000).

9. Equivalent Fractions

Which is equivalent to $\frac{4}{7}$?

• To find equivalent fractions, multiply both the numerator and the denominator by the same number.
• For option A: $\frac{4 \times 2}{7 \times 2} = \frac{8}{14}$, which is correct.
  • The correct option is A $\frac{8}{14}$.

10. Total Money as Fraction

• The image shows $2.85 (2 dollars and 85 cents).
• $0.85 is $\frac{85}{100}$.
  • The correct option is B ($2.85, $\frac{85}{100}$).

11. Conversion: Meters to Centimeters

3 meters = ? centimeters:

• 1 meter = 100 centimeters, so 3 meters = $3 \times 100 = 300$ centimeters.
  • The correct option is C (300).

12. Mixed Fraction

Convert $\frac{22}{3}$ to a mixed number:

• $22 \div 3 = 7$ remainder 1, so $\frac{22}{3} = 7 \frac{1}{3}$.
  • The correct option is B $7 \frac{1}{3}$.
