To determine how many pancakes Jaylen can make with 1 liter of pancake mixture, we can set up a simple equation.
Let \( x \) be the number of pancakes Jaylen can make. Since each pancake requires \( \frac{1}{4} \) liter of mixture, we can express the total amount of mixture used for \( x \) pancakes as:
\[ \frac{1}{4}x \]
Given that Jaylen has 1 liter of pancake mixture, we can set up the equation:
\[ \frac{1}{4}x = 1 \]
Now, to solve for \( x \), we can multiply both sides of the equation by 4 to eliminate the fraction:
\[ x = 1 \times 4 \]
\[ x = 4 \]
Thus, Jaylen can make 4 pancakes with the whole mixture.
