1. The problem asks to find 2 possible equations that correspond to the given 2x2 grid where each box contains the value $\frac{1}{5}$. The grid has arrows and numbers 5, +, 4, -, and 0 with $x$ crossed out. 2. Since each box has the same value $\frac{1}{5}$, one natural equation is that the sum of all four boxes equals 1: $$\frac{1}{5} + \frac{1}{5} + \frac{1}{5} + \frac{1}{5} = 4 \times \frac{1}{5} = \frac{4}{5} \neq 1$$ But since the sum is $\frac{4}{5}$, not 1, we consider the numbers 5, +, 4, -, and 0 as clues. 3. One possible equation is: $$5 + 4 - x = 0$$ Given $x$ is crossed out, solving for $x$: $$5 + 4 - x = 0$$ $$9 - x = 0$$ $$x = 9$$ 4. Another possible equation relates to the values in the boxes. Since each box is $\frac{1}{5}$, multiplying by 5 gives 1: $$5 \times \frac{1}{5} = 1$$ So a second equation could be: $$5 \times \frac{1}{5} = 1$$ 5. Summary: - Equation 1: $$5 + 4 - x = 0$$ with solution $$x=9$$ - Equation 2: $$5 \times \frac{1}{5} = 1$$ These two equations fit the numbers and values shown in the grid and arrows.
