Question

the butterfly sits on flower change to past simple​

Answer 1

Answer:

the butterfly sat on the flower

Answer 2

The butterfly sat on the flower.

The tense of the sentence in question is in the form of the simple present tense. This can be seen by the use of the word 'sits', which denotes the action of sitting in the present.

To convert to simple past tense, we change the word 'sits' to its past tense form, which is 'sat'.

Doing this changes the entire sentence to the simple past tense and no further changes are needed.
