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].
