Alright! So to solve these questions, you need to find out the difference. You can use ratios to solve this. For example, question #25:

A class had 30 pupils at the beginning of this school term, but now has 5 more pupils. What is the percent of increase?

The question is basically asking how much 5 is in ratio to 30. So just divide 5 (the given amount) by 30 (the total amount). The answer is 0.16, or 16%

koban [17]

Answer:

The greatest amount Ghani could make of fizzy drink is <u>480 ml</u>.

Step-by-step explanation:

Given:

Ghani is going o use these instructions to make a fizzy drink. Mix 5 parts of lime juice with 3 parts of lemonade. Ghani thinks that he has 300ml of lime juice and 200 ml of lemonade.

Now, to find the greatest amount of fizzy Ghani could make.

Let the ml of lemonade be x.

As, for making fizzy drink 5 parts of lime juice with 3 parts of lemonade are mixed.

So, 5 is equivalent to 3.

Ghani has 300ml of lime juice.

Thus, 300 is equivalent to x.

Now, to get the ml of lemonade we use cross multiplication method:

\frac{5}{3} = \frac{300}{x}

<em>By cross multiplying we get:</em>

<em />5x=900<em />

<em>Dividing both sides by 5 we get:</em>

x=180\ ml.

Hence, the lemonade is 180 ml.

Now, we add the quantity of 180 ml lemonade with 300 ml lime juice to get the fizzy drink:

180+300\\\\=480\ ml.

Therefore, the greatest amount Ghani could make of fizzy drink is 480 ml.
