The second one is correct
8:15 or 8 to 15 would be the ratio because you compare 8 quarters to 15 coins.
First, find a lowest common denominator. The lcd in this equation os 8 so your new fractions would be 4/8, 6/8, and 7/8. You add the numerators (top numbers), which equals 17/8. Then you simplify to 2 1/8 liters.
Answer:
26
Step-by-step explanation:
Plug in 15 for y in the first problem so instead of y=x-11 it would be 15=x-11
15=x-11
+11= +11 (you want to add 11 to both sides to get x by its self)
26=x
