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
