Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
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?

### Response:
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=1440>>1440 grams.
Since Sophia ate 1/6 of the pie, then she ate 1/6*1440 = <<1440*1/6=240>>240 grams of the pie.
