Mandi has 42 stamps. She wants to put her stamps in a folder. If she puts 6 stamps on each page, how could she find the number of pages needed? Group of answer choices A. 42 : 6 = n

B. 42 * 6 = n

C. 42 + 6 = n

D. 42 - 6 = n

A. 42:6

Step-by-step explanation:

If Mandi has total number of 42 stamps and she needs to put 6 stamps on each page, to find the number of pages she needs to stamp, we will use the following relationship;

Since there are 6stamps per page, i. e 6stamps = 1page

42stamps = x number of pages

where x is unknown.

Cross multiplying to get 'x' we have;

42stamps * 1page = 6stamps * x pages

x pages = 42stamps * 1page/6stamps

x pages = 42/6

The expression to find the number of pages for 42stamps needed will therefore be 42:6

Answer is: A) 42/6=n
