Calculation of the Number of Pancakes

To determine the number of pancakes that the mother prepared, we can use the information provided. During dinner, 9 pancakes were eaten, leaving one-third of the total pancakes remaining.

Let's assume that the total number of pancakes the mother prepared is represented by the variable "x". According to the given information, one-third of the pancakes remained after dinner. This can be expressed as:

x - 9 = (1/3)x

To solve this equation, we can multiply both sides by 3 to eliminate the fraction:

3(x - 9) = x

Expanding the equation:

3x - 27 = x

Next, we can subtract "x" from both sides:

3x - x = 27

Simplifying the equation:

2x = 27

Finally, we can solve for "x" by dividing both sides by 2:

x = 27 / 2

Therefore, the mother prepared 13.5 pancakes.

Please note that it is not possible to have half a pancake, so it is likely that the number of pancakes prepared was rounded up or down to the nearest whole number.
