A tin of oil weighs 16.8 kg. What is the weight of 45 such tins?

Options

A. 8556 kg
B. 756 kg
C. 7566 kg
D. 7756 kg

Answer

To find the weight of 45 tins of oil, we can follow these steps:

### Step 1: Identify the weight of one tin
The weight of one tin of oil is given as 16.8 kg.

### Step 2: Set up the multiplication
To find the total weight of 45 tins, we need to multiply the weight of one tin by the number of tins:
\[ \text{Total weight} = \text{Weight of one tin} \times \text{Number of tins} \]
\[ \text{Total weight} = 16.8 \, \text{kg} \times 45 \]

### Step 3: Multiply the numbers
To perform the multiplication, we can first remove the decimal from 16.8. We can express it as:
\[ 16.8 = \frac{168}{10} \]
Now, we can multiply:
\[ \frac{168}{10} \times 45 = \frac{168 \times 45}{10} \]

### Step 4: Calculate \(168 \times 45\)
Now we can calculate \(168 \times 45\):
\[ 168 \times 45 = 7560 \]

### Step 5: Divide by 10
Now, we need to divide by 10 to account for the decimal we removed earlier:
\[ \frac{7560}{10} = 756 \]

### Step 6: Conclusion
Thus, the total weight of 45 tins of oil is:
\[ \text{Total weight} = 756 \, \text{kg} \]
