1. The problem involves filling in missing values in a table with fractions and decimals. 2. We start by understanding the given values: fractions like $\frac{1}{3}$, $-\frac{1}{4}$, $-\frac{2}{3}$, decimals like $0.7$, and a fraction $\frac{31}{30}$. 3. Convert fractions to decimals for easier comparison and calculation: - $\frac{1}{3} \approx 0.333$ - $-\frac{1}{4} = -0.25$ - $-\frac{2}{3} \approx -0.666$ - $\frac{31}{30} \approx 1.033$ 4. The top row has decimals $-0.6$ and $-1.2$. 5. To fill the table, match or calculate the missing values by adding or subtracting the given numbers in rows and columns. 6. For example, adding $\frac{1}{3} \approx 0.333$ to $-0.6$ gives $0.333 + (-0.6) = -0.267$. 7. Similarly, subtracting $\frac{1}{4} = 0.25$ from $-1.2$ gives $-1.2 - 0.25 = -1.45$. 8. Continue this process for all missing entries by performing the appropriate arithmetic operations. 9. This method ensures all table entries are consistent and correctly calculated. Final answer: Use decimal equivalents and arithmetic operations to fill the table values accordingly.
