Part A.
Consider a punch containing L liters.
60% of these that is
is grape juice, and the rest, 0.4 L is lemon-soda.
so, for the variable L, the total amount of punch, the total amount of grape juice is 0.6 L
and the amount of lemon soda in the punch is 0.4L
Part B.
For L=2, we substitute and get:
0.6 L=0.6 * 2 liters = 1.2 liters of grape juice
0.4 L = 0.4 * 2 liters = 0.8 liters of lemon soda.

Answer:
The ratio of used stamps and total stamps can be represented by three fifths.
Step-by-step explanation:
It is give that Jamal has 4 new stamps and 6 used stamps.
New stamps = 4
Used stamps = 6
Total stamps = New stamps + Used stamps = 4 + 6 = 10
We need to find the ratio that can be represented by three fifths
Therefore, the ratio of used stamps and total stamps can be represented by three fifths.
