Question 7. Rahul has 192 toy cars. He put them equally in 6 boxes. How many toy cars will he put in each box? How many toy cars are left over?
Answer: To find out how many toy cars Rahul put in each box and how many were left over, we need to divide the total number of cars (192) by the number of boxes (6).
\( 192 \div 6 = 32 \)
The quotient is 32, and the remainder is 0. So, Rahul put 32 toys in each box, and there were no toys left over. This shows the cars were shared perfectly.

Question 8. Akila has 495 photographs to put album. She can put 9 photographs on each page. How many pages can she fill?
Answer: To find out how many pages Akila can fill, we need to divide the total number of photographs (495) by the number of photographs she puts on each page (9).
\( 495 \div 9 = 55 \)
The quotient is 55, and the remainder is 0. So, Akila filled 55 pages completely. Division helps us organize items into equal groups.
In simple words: Akila has 495 photos and puts 9 on each page. She can fill 55 pages with all her photos.

🎯 Exam Tip: When a word problem asks "how many" of something, division is often the key operation, especially if it involves sharing or grouping.
