Dariusz spends 7 3/5 hours practicing a dance routine one week. What is this number expressed as an improper fraction

Answer 1

To convert the mixed number \( 7 \frac{3}{5} \) to an improper fraction, we can follow these steps:

1. Multiply the whole number part by the denominator: \( 7 \times 5 = 35 \).

2. Add the numerator to this result: \( 35 + 3 = 38 \).

3. Put this result over the original denominator: \( \frac{38}{5} \).

Thus, the mixed number \( 7 \frac{3}{5} \) expressed as an improper fraction is \( \frac{38}{5} \).
