1.8 is the square root of 3.24
Answer:
15 packages
Step-by-step explanation:
Set up a proportion, where x is the number of packages she can wrap with 2.5 rolls of wrapping paper:
= 
Cross multiply and solve for x:
0.5x = 7.5
x = 15
So, with 2.5 rolls of wrapping paper, she can wrap 15 packages
I think it's a pattern, so x would be 3 and y would be 5 for the first one
x would be 20 for the second
and i dont even do word problems so...
I believe that the answer is 7/18, at least that’s what I got.
