Answer:
3 meals
Step-by-step explanation:
The card costs $6, so we will subtract that from $15 because it is the starting amount. Karla can't buy these meals for $3 without $6. Anyways, 15-6 is 9. Each meal costs $3 so we'll then divide 9 by 3, which gives us our answer: she bought 3 meals.
The required proportion of the blue paint is 18 liters.
Given that,
The ratio of yellow and blue colors is 2:3
The proportion of the yellow color is 12 liters.
The proportion of blue color is to be determined.
<h3>What is the Ratio?</h3>
The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
Let the proportion of the blue color is x,
Now, the ratio can be given as
12 / x = 2 / 3
x = 12 * 3 / 2
x = 18
Thus, the required proportion of the blue paint is 18 liters.
