Answer :

To solve the expression [tex]\( 1.9 \cdot \left(\frac{1}{4}\right) \)[/tex], follow these steps:

1. Identify the numbers involved:
- The first number is 1.9.
- The second number is the fraction [tex]\( \frac{1}{4} \)[/tex].

2. Multiply the numbers:
- When you multiply 1.9 by [tex]\( \frac{1}{4} \)[/tex], you are essentially dividing 1.9 by 4.

3. Calculate the multiplication:
- Multiplying 1.9 by [tex]\( \frac{1}{4} \)[/tex] gives you 0.475.

Therefore, [tex]\( 1.9 \cdot \left(\frac{1}{4}\right) = 0.475 \)[/tex].

So, the answer is:
[tex]\[ 1.9 \cdot \left(\frac{1}{4}\right) = 0.475 \][/tex]
