Answer

To find the fraction of 450 grams out of 3 kg, we can follow these steps:

### Step 1: Convert kilograms to grams
We know that:
1 kg = 1000 grams

So, to convert 3 kg to grams:
\[ 3 \, \text{kg} = 3 \times 1000 \, \text{grams} = 3000 \, \text{grams} \]

### Step 2: Set up the fraction
Now we can express the fraction of 450 grams out of 3000 grams:
\[ \text{Fraction} = \frac{450 \, \text{grams}}{3000 \, \text{grams}} \]

### Step 3: Simplify the fraction
Next, we simplify the fraction \(\frac{450}{3000}\). To do this, we can find the greatest common divisor (GCD) of 450 and 3000.

First, we can divide both the numerator and the denominator by 150 (since both numbers are divisible by 150):
\[ \frac{450 \div 150}{3000 \div 150} = \frac{3}{20} \]

### Final Answer
Thus, the fraction of 450 grams out of 3 kg is:
\[ \frac{3}{20} \]
