Question

make true equations by dragging and flipping the cards. try to use as few flips as possible. check my work card flips: 0

Explanation:

Step1: Analyze first equation

We need to find a combination for $a + b - c=0$. Let's try values. If $a = \frac{1}{2}$, $b=\frac{1}{4}$, $c=\frac{3}{4}$, then $\frac{1}{2}+\frac{1}{4}-\frac{3}{4}=\frac{2 + 1-3}{4}=0$.

Step2: Analyze second equation

We need to find a combination for $d - e + f = 1$. If $d = 1$, $e=\frac{1}{8}$, $f=\frac{1}{8}$, then $1-\frac{1}{8}+\frac{1}{8}=1$.

Answer:

First equation: $\frac{1}{2}+\frac{1}{4}-\frac{3}{4}=0$
Second equation: $1-\frac{1}{8}+\frac{1}{8}=1$
