Transcript text: \[ \frac{9+7}{16} \] $(24+12) \div 3^{2}$

Solution

Step 1: Simplify the Fraction

The first expression given is:

\[ \frac{9+7}{16} \]

First, simplify the numerator:

\[ 9 + 7 = 16 \]

So the expression becomes:

\[ \frac{16}{16} \]

Step 2: Simplify the Fraction Further

Now, simplify the fraction:

\[ \frac{16}{16} = 1 \]

Step 3: Evaluate the Second Expression

The second expression given is:

\[ (24+12) \div 3^{2} \]

First, simplify the expression inside the parentheses:

\[ 24 + 12 = 36 \]

Now, evaluate the exponent:

\[ 3^{2} = 9 \]

So the expression becomes:

\[ 36 \div 9 \]

Step 4: Perform the Division
