1. The problem is to express the mixed number 7 3/8 as an improper fraction. 2. A mixed number consists of a whole number and a fraction. To convert it to an improper fraction, use the formula: $$\text{Improper fraction} = \frac{(\text{Whole number} \times \text{Denominator}) + \text{Numerator}}{\text{Denominator}}$$ 3. Here, the whole number is 7, the numerator is 3, and the denominator is 8. 4. Substitute these values into the formula: $$\frac{(7 \times 8) + 3}{8}$$ 5. Calculate the numerator: $$7 \times 8 = 56$$ $$56 + 3 = 59$$ 6. So the improper fraction is: $$\frac{59}{8}$$ 7. Therefore, 7 3/8 expressed as an improper fraction is $\frac{59}{8}$.
