Step-by-step explanation:
The ratio of orange juice to ginger ale is 2:5.
Add 2 + 5 = 7.
The ratio of orange juice to ginger ale to total drink is 2:5:7.
a) The fraction of orange juice is 2/7 of the total drink.
To make 2 L, you will need 2/7 of 2 L to be orange juice.
2/7 * 2 L = 4/7 L = 0.57 L
b) The fraction of ginger ale is 5/7 of the total drink.
5/7 * 5 L = 25/7 L = 3.57 L

Answer:
Statement expressed by Trent is RIGHT.

Step-by-step explanation:
Here, the given expression is:
( to show) : 
Now, as we know by DISTRIBUTIVE PROPERTY:
A (B + C) = AB + AC
Consider the RHS of the expression:
(p +30)(p+0) = (p +30)(p) ............ ( a + 0 = a for all a)
Simplifying (p +30)(p) by distributive property, we get:

⇒ Left side = Right side
Hence, statement expressed by Trent is RIGHT.
