A subject is the part of a sentence that performs a verb( an action) in a sentence.

The predicate is the part of a sentence that contains the verb.

Explanation:

A subject is the one who does the action and performing something.

For example, He likes to play, Sara loves flowers. in the following sentences, HE and Sara are the subjects as they doing and performing something.

And the predicate is the verb and the rest of the sentence and not the subject.

For example; He likes to play, Sara loves flowers. in these sentences likes to play and loves flowers are the predicates of the sentences.

1)The bunnies like to play in the sunshine( The bunnies are the subject and "like to play in the sunshine" is the predicate),

"they"(subject) and "will often come right up to you"(Predicate)

"You"(subject) and "offer them something to eat"(Predicate).

Explanation:

First convert both weights to grams.

South African;

1 kg = 1,000 grams

105kg = 105 * 1,000 grams

= 105,000 grams

American

453.592 g = 1 pound

230 pounds = 453.592 * 230

= ‭104,326 grams

Difference

= 105,000 - 104,326

= 674 grams

In kg:

= 674/1,000

= 0.674
