Question

Sam has 12 black and white photos and 18 color photos.he wants to put the photos in equal rows so each row has either black and white photos only or color photos only. in how many rows can Sam arrange the photos

Answer 1

Explanation:

First you have to find the GCF (greatest common factor) and the GCF is 6

Then you have to multiply 3×6 = 18, 2×6 = 12

Next add 3 + 2 = 5 because I added the first digits of the multiplying thinge

Write it like this (if you want):

Sam can arrange his photos in 5 rows

Answer 2

The question is asking us to determine the number of rows in which Sam can arrange his 12 black and white and 18 color photos. Sam wants to put them in the equal rows so that each row has either black and white photos only or color photos only. We have to find the GCF ( the Greatest Common Factor ) of 18 and 12. GCF ( 18, 12 ) = 6. So there should be 6 photos in each row if they have to be equal ( the equal number of photos in every row ). 18 = 6 * 3 and 12 = 6 * 2. Therefore the number of the rows is : 3 + 2 = 5. Answer: Sam can arrange his photos in 5 rows.
