Question

Soumik has done all the sums correctly (change the voice ​

Answer 1

Answer:

all the sums have been correctly done by Soumik.

Answer 2

The complete sentence should be:

All the sums have been correctly done by Soumik.

* The sentence is given in the active voice which needs to be converted into the passive voice.

* In case of active voice, we start the sentence with the subject( here it is Soumik) followed by the verb( 'has done' ) and finally the object(sums).

* In case of passive voice, the subject interchanges its position with the object and so a sentence starts with the object.
