Yes because 4 times 5 is 20 and 15 + 5 is 20
If 3 ice cream cones cost 8.25 how much do 2 ice cream cones cost?
1 cone cost
8.25 : 3 = 2.75
2 cones cost
2.75 * 2 = 5.5
or
(8.25 : 3) * 2 = 5.5
It would be a 2:1 ratio because sides AC and DF are 8:4 which simplifies to 2:1
Hope this helps!
There is nothing there to work with
