1-24/36

To solve the expression \(1 - \frac{24}{36}\), first simplify the fraction:

\[ \frac{24}{36} = \frac{2 \times 12}{3 \times 12} = \frac{2}{3} \]

Now substitute back into the expression:

\[ 1 - \frac{2}{3} \]

To perform the subtraction, convert \(1\) to a fraction with a denominator of \(3\):

\[ 1 = \frac{3}{3} \]

Now subtract the fractions:

\[ \frac{3}{3} - \frac{2}{3} = \frac{3 - 2}{3} = \frac{1}{3} \]

Thus, the final result is:

\[ \frac{1}{3} \]
