The first step in changing a mixed number to an improper fraction is to multiply the whole number part by the denominator of the fractional part.
For example, if you have the mixed number \( 2 \frac{3}{4} \):
1. Multiply the whole number (2) by the denominator (4): \( 2 \times 4 = 8 \).
2. Then, add the result to the numerator (3): \( 8 + 3 = 11 \).
3. Finally, place this sum over the original denominator (4), resulting in the improper fraction \( \frac{11}{4} \).
So, the first step is to multiply the whole number by the denominator.
