Rūtas vecmāmiņa gatavojas cept maizes kukulīšus, katram kukulītim ir nepieciešams 3/10 kg rudzu miltu. Rūta no veikala atnesa 2 kilogramus miltu. Vai vecmāmiņai pietiks ar Rūtas atnestajiem miltiem, ja viņa nolēmusi cept 9 vienādus kukulīšus? 1. Cik kg miltu nepieciešams 9 kukulīšiem? 2. Kāda daļa no kilograma ?

Let's solve this problem step-by-step!

First, we need to figure out how many kilograms of flour are needed for 9 cookies.

Each cookie requires $$\frac{3}{10}$$ kg of flour.

For 9 cookies, the total flour needed will be:

• \[ 9 \times \frac{3}{10} = \frac{9 \times 3}{10} = \frac{27}{10} \text{ kg} \]

Now, let's convert this to a mixed number or decimal to make it easier to compare with the amount Rūta brought.

• \[ \frac{27}{10} = 2 \frac{7}{10} = 2.7 \text{ kg} \]

Rūta brought 2 kilograms of flour.

We need 2.7 kg, and Rūta has 2 kg. This means she does NOT have enough flour.

Now let's answer the specific questions:

1. Cik kg miltu nepieciešams 9 kukulīšiem? (How many kg of flour are needed for 9 cookies?)
• We calculated this above: \[ \frac{27}{10} \] kg.
2. Kāda daļa no kilograma (What fraction of a kilogram...)? This question seems incomplete in the image provided. Based on the context, it might be asking what fraction of the required flour Rūta has, or what fraction she is short. However, without a complete question, we'll assume it relates to the total amount needed. The amount needed is \[ \frac{27}{10} \] kg. If the question is asking how much more flour is needed, that would be \[ 2.7 - 2 = 0.7 \text{ kg} \] or \[ \frac{7}{10} \] kg.

Since the image has input fields, let's fill them based on our calculations.

For question 1, the answer is $$\frac{27}{10}$$ kg.

For question 2, assuming it's asking for the amount *needed* as a fraction of a kilogram (which is a bit of an odd phrasing), it's still \[ \frac{27}{10} \] kg. If it's asking for the *shortage* as a fraction of a kilogram, it would be \[ \frac{7}{10} \] kg.

Based on the layout, it looks like the first box in Q1 is for the whole number part and the fraction boxes are for the numerator and denominator.

• \[ 9 \text{ kukulīšiem nepieciešami } \frac{27}{10} \text{ kg miltu, kas ir } 2 \frac{7}{10} \text{ kg.} \]
• For Q2, if it's asking for the shortage: \[ \frac{7}{10} \] kg.

Summary:

• Amount needed for 9 cookies: $$\frac{27}{10}$$ kg (or 2.7 kg).
• Amount Rūta has: 2 kg.
• Conclusion: Rūta does not have enough flour.

Answer to question 1: The amount of flour needed for 9 cookies is $$\frac{27}{10}$$ kg.

Answer to question 2: If the question is asking for the amount of flour *short* in kilograms, it's $$\frac{7}{10}$$ kg.

Final Answer:

1. Cik kg miltu nepieciešams 9 kukulīšiem? 2 kg 7/10 kg

2. Kāda daļa no kilograma ? 7/10 kg
