145 divided by 7 =20.71
a little sketch on my answer <span />
8 printers for $145 each is a total of $1160.
3 laptops for $439 is a total of $1317.
Therefore, the price of 3 laptops for $439 each cost more than 8 printers for $145 each.
Yes. 3/15 can still be simplified
Divide 3 from numerator and denomoinator.
3/3 = 1
15/3 = 5
1/5 is the simplified form.
hope this helps
