Answer :

Sure, let's break down the given mathematical expression step by step.

1. Simplify the fractions:

The first fraction is [tex]\(\frac{3}{6}\)[/tex]. This can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 3:

[tex]\[ \frac{3}{6} = \frac{3 \div 3}{6 \div 3} = \frac{1}{2} \][/tex]

The second fraction is already [tex]\(\frac{1}{2}\)[/tex], so there is no need to simplify it further.

2. Calculate the product of the two fractions:

Now we multiply the two fractions together:

[tex]\[ \frac{1}{2} \times \frac{1}{2} = \frac{1 \times 1}{2 \times 2} = \frac{1}{4} \][/tex]

3. Add the product to the initial value:

The initial value given is 15. We need to add the product of the fractions, [tex]\(\frac{1}{4}\)[/tex], to this initial value:

[tex]\[ 15 + \frac{1}{4} = 15 + 0.25 = 15.25 \][/tex]

So, putting it all together, the simplified expression is:

[tex]\[ 15 + \left(\frac{3}{6} \times \frac{1}{2}\right) = 15.25 \][/tex]

To summarize:
- The product of [tex]\(\frac{3}{6}\)[/tex] and [tex]\(\frac{1}{2}\)[/tex] is [tex]\(\frac{1}{4}\)[/tex].
- Adding [tex]\(\frac{1}{4}\)[/tex] to the initial value of 15 gives the final result of 15.25.

Thus, the detailed step-by-step solution shows that:

[tex]\[ \boxed{15.25} \][/tex]
