how many groups of 14 are in 8442?

There are 311 groups of 27 in 8397.

There are 522 groups of 18 in 9396.

There are 603 groups of 14 in 8442.

Step-by-step explanation:

Division is the key to getting the answer to this question.

8397 / 27 = 311

9396 / 18 = 522

8442 / 14 = 603

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.
