Let's go through the ratio tables one by one and fill in the missing values.

Table 1:

• The ratio pattern is increasing by a factor of 3.
• First column: $1 \to 3 \to 6$.
• Second column: $3 \to 9 \to 18$.
• Since 1 multiplied by 3 gives 3, and 3 multiplied by 3 gives 9, we expect $6 \times 3 = 18$. So, the missing value in the last box of the first column is 6.

Table 2:

• The ratio pattern shows an increase by a factor of 3.
• First row: $11 \to 33 \to 54 \to 162$.
• Second row: $6 \to 18 \to 30 \to 42$.
• The missing value in the third box is already filled as 54.

Table 3:

• The ratio seems to involve multiplication by a factor of 5.
• First row: $21 \to 35 \to \text{missing}$.
• Second row: $8 \to 40 \to 72$.
• Let's find the missing value: $35 \div 5 = 7$, and similarly $8 \times 9 = 72$, so $8 \times 5 = 40$.
• The missing value would be the one corresponding to $35 \times 2 = 70$.

Table 4:

• Incomplete, seems to follow the ratio rule of 2.
• First row: $3 \to 9 \to 12 \to \text{missing}$.
• Second row: (7 \to 14 \to \textul.... %@helpers
