Hey
so you will know when two numbers are common as the same numbers can be divided into them without leaving a remainder
say for instance the common factors for 12 and 16 are:
1, 2 and 4
because those numbers can be divided into 12 and 16 without remainders
same as 15 and 30:
1, 3, 5 and 15
Three ways are:
<u>In Fraction Form:</u> 
<u>In Ratio its</u>: What you said
7:30 And
In a Percent Form Its:
0.23- %(I got that from dividing 7 by 30.)
Hope IT helped You. :D

Answer:
$15, $20
Step-by-step explanation:
Let u represent the unit price of umbrellas and h the unit price of hats.
Case 1: A. spent $80.
Then $80 = 4u + 5($4), or $80 = $20 + 4u, or $60 = 4u, or
u = $15/umbrella.
Case 2: A spent $100.
Then $100 = 4u + 5($4), or $100 = $20 + 4u, or $80 = 4u, or
u = $20/umbrella.
The least A. could have spent on a single umbrella was $15, and the most was $20.
