Georgena has 84 pictures she wants to organize in a photo album.How many more pages of the album will be used if Georgena puts 4 pictures on each page than if she puts 6 pictures on each page?
You would divide 84 by 4 and 84 by 6 and then take those 2 numbers and substract to get your answer. 84 divided by 4 is 21 and 84 divided by 6 is 14 so 21-14=7. I hope this helps!
