Question:

Ellen mixed ¼ kg of flour with ²/9 kg of sugar.

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete. However, question that are likely to be asked are.

- What's the weight of the total mixture in grams

- What percentage of the mixture is sugar

To solve (1);

We simply add both weights together

But first, the units must be converted to grams.

1kg = 1000 grams

So,

¼kg = ¼ * 1000 g

¼kg = 250 g

²/9kg = ²/9 * 1000

²/9kg = 2000/9

²/9kg = 222.2 g

Add these results

Total = 250g + 222.2g

Total = 472 g

The result can be written in different ways

1. 472 grams

2. About 500 grams

If converted back to kg

472 grams = 472/1000 kg

472 grams = 0.472 kg.

So, the result can also be written as

3. 0.472 kg

4. About 0.5kg (½kg)

To solve (2)

What percentage of the mixture is sugar

To do this, we simply divide the size of sugar by the total size of the mixture.

From (1) above

Sugar = 250g

Total = 472g

Percentage of sugar = 250/472

Percentage of sugar = 0.5297

Percentage of sugar = 0.5297 * 100%

Percentage of sugar = 52.97%
