1 answer

To solve the problem \(1.35 \times 1.4\), we can express each number in a more manageable form by converting them into fractions or whole numbers.

  1. \(1.35\) can be expressed as \(135 \times 0.01\) or \(135 \times \frac{1}{100}\).
  2. \(1.4\) can be expressed as \(14 \times 0.1\) or \(14 \times \frac{1}{10}\).

Now, for the multiplication:

\[ 1.35 \times 1.4 = (135 \times \frac{1}{100}) \times (14 \times \frac{1}{10}) \]

This can be rearranged as:

\[ = 135 \times 14 \times \frac{1}{100} \times \frac{1}{10} \]

This matches with one of the formats you provided.

Among the options listed:

  • The correct option would be: \(135 \times \frac{1}{100} \times 14 \times \frac{1}{10}\) This shows that the multiplication of the whole numbers is taking place first \( (135 \times 14) \) and then the decimal adjustments \( \left(\frac{1}{100} \times \frac{1}{10}\right) \).

So the correct method can be summarized as:

\[ (135 \times 14) \times (\frac{1}{100} \times \frac{1}{10}) \]

If the options correspond to this framework, then you would identify that as the correct choice.
