Answer :

Let's solve the given expression step-by-step: [tex]\(\left(\frac{7+5}{5+5}\right)\)[/tex].

1. Calculate the numerator:
[tex]\[ 7 + 5 = 12 \][/tex]

2. Calculate the denominator:
[tex]\[ 5 + 5 = 10 \][/tex]

3. Form the fraction with the calculated values:
[tex]\[ \frac{12}{10} \][/tex]

4. Simplify the fraction:
[tex]\[ \frac{12}{10} = 1.2 \][/tex]

So, the final result is:
[tex]\[ \left(\frac{7+5}{5+5}\right) = 1.2 \][/tex]

Thus, [tex]\(\left(\frac{7+5}{5+5}\right) = 1.2\)[/tex].
