Sophia ate 1/6 of her pie and she put the rest on the fridge. If the pie left in the fridge weighs 1200 grams, how many grams did Sophia eat? Give me reasons, before answering the question

If Sophia ate 1 / 6 of the pie, then 6 / 6 - 1 / 6 = 5 / 6 is left in the fridge. Let x be the pie's original weight. The current weight of the pie can be described by 5x / 6 = 1200 grams. So, 5x = 7200. And, the original weight is x = 1440 grams. So, Sophia ate 1440 grams original - 1200 grams after = 240 grams of pie. So the final answer is 240.
