Evaluate the
`3.7xx4.5`

Answer

To evaluate \( 3.7 \times 4.5 \), we can follow these steps:

### Step 1: Convert the decimals to fractions
We can convert the decimals into fractions to make multiplication easier.
- \( 3.7 \) can be expressed as \( \frac{37}{10} \) (since there is one digit after the decimal).
- \( 4.5 \) can be expressed as \( \frac{45}{10} \) (for the same reason).

### Step 2: Multiply the fractions
Now we can multiply these two fractions:
\[ 3.7 \times 4.5 = \frac{37}{10} \times \frac{45}{10} = \frac{37 \times 45}{10 \times 10} = \frac{1665}{100} \]

### Step 3: Perform the multiplication
Next, we need to calculate \( 37 \times 45 \):
- Break it down:
- \( 37 \times 5 = 185 \)
- \( 37 \times 40 = 1480 \)
- Adding these results together:
\[ 185 + 1480 = 1665 \]

### Step 4: Place the decimal point
Now, we have \( \frac{1665}{100} \). To convert this back to decimal form, we need to place the decimal point:
- Since the denominator is \( 100 \), we move the decimal point two places to the left.
- Thus, \( 1665 \) becomes \( 16.65 \).

### Final Answer
Therefore, \( 3.7 \times 4.5 = 16.65 \).
