Great! I see that you're working on ratios, specifically with ratio or pattern tables. Let me guide you step by step to solve this.

First Table (Top):

The table contains four rows, where some cells are blank, and the goal is likely to find the missing values by using ratios.

Observations:

• The first row: 20, 15, blank, 12, 100.
• The second row: blank, blank, 60, blank, blank.

To solve:

1. Identify the relationship between the first and second rows (they likely follow a ratio).
2. Use proportional relationships to fill in the blanks.

For example, look at the last column where 100 corresponds to a blank value in the second row. Using a consistent ratio, find the proportionality factor. Similarly, calculate for the other blanks.

Second Table (Bottom):

The table contains four rows with some cells blank.

Observations:

• The first row: blank, blank, blank, 10.
• The second row: 30, blank, 18, 20.

Here, similar to the first table, determine the ratios across rows and columns to find the missing values.

Would you like me to solve each blank step by step and explain the ratios? Let me know!
