To solve this expression using the order of operations (PEMDAS), we first perform the multiplication.
1/2 + 1/9 * 1/5 = 1/2 + 1/45
Next, we need to find a common denominator to add the two fractions. The least common denominator between 2 and 45 is 90.
Converting 1/2 to have a denominator of 90:
1/2 = 45/90
So, the expression becomes:
45/90 + 1/45 = (45 + 2)/90 = 47/90
Therefore, 1/2 + 1/9 * 1/5 = 47/90.
1/2 + 1/9 * 1/5 = 1/2 + 1/45
