1. The problem is to complete the ratio table where the first column has some missing values and the second column is given as 1, 2, 4, 5, 8. 2. The given pairs are (12,1) and (24,2). We see that the ratio between the first and second columns is constant because it's a ratio table. 3. Calculate the ratio from the first pair: $$\frac{12}{1} = 12$$. This means for every 1 in the second column, the first column is 12. 4. Check the second pair: $$\frac{24}{2} = 12$$, confirming the ratio is consistent. 5. Use this ratio to find the missing values in the first column by multiplying the second column values by 12. 6. For the third row: $$12 \times 4 = 48$$. 7. For the fourth row: $$12 \times 5 = 60$$. 8. For the fifth row: $$12 \times 8 = 96$$. 9. The completed ratio table is: | First Column | Second Column | |--------------|---------------| | 12 | 1 | | 24 | 2 | | 48 | 4 | | 60 | 5 | | 96 | 8 |
