Explanation:

Step1: Solve Group A problems

A (missing number):

Identify non-multiple of 3:
$15\div3=5$, $27\div3=9$, $31\div3\approx10.33$, so 31 is excluded.

A (calculations):

1. Divide 110 by 11: $110\div11=10$
2. Multiply 10 and 11: $10\times11=110$
3. Multiply 10 and 10: $10\times10=100$
4. Divide 110 by 10: $110\div10=11$

A (symbol comparison):

Calculate both sides: $8+5=13$, $6+8=14$. $13<14$, so use $<$.

Step2: Solve Group B problems

B (false statements):

1. $4\times8=32$, $6\times6=36$ → $32

eq36$, true (not true)

1. $9\times7=63$, $8\times8=64$ → $63>64$ is false
2. $5\times7=35$, $4\times9=36$ → $35<36$, true
3. $24\div6=4$, $8\div2=4$ → $4

eq4$ is false
False statements: 7, 9

B (jogger distance):

Choose unit for distance: 6 kilometers

B (shorter length):

Convert units: $1\ \text{m}=100\ \text{cm}$, so 1 m is shorter.

Step3: Solve Group C problems

C (angle type):

Right angle matches the diagram: 5. a right

C (baseball boxes):

Total balls needed: $18\times3=54$
Boxes needed: $\lceil\frac{54}{8}
ceil=7$ (since $6\times8=48<54$, $7\times8=56\geq54$)

Step4: Solve Group D problems

D (crayon ratio):

Red crayons: 5, total: 20. Ratio: $\frac{5}{20}=1:4$ → 40. 1:4

D (age difference):

Rita's age: $22+5=27$
Candye's age: $27-7=20$
Difference: $22-20=2$

Answer:

Group A:

• Missing number: 31
• 5. $10$
• 6. $110$
• 7. $100$
• 8. $11$
• Symbol: $<$

Group B:

• False statements: 7, 9
• Jogger distance: 6 kilometers
• Shorter length: 1 m

Group C:

• Angle type: 5. a right
• Baseball boxes: 7

Group D:

• Crayon ratio: 40. 1:4
• Age difference: 2
