Решение:
- \( 7,27 = \frac{727}{100} \)
- \( 4,99 = \frac{499}{100} \)
- \( 7,27 - 4,99 = \frac{727}{100} - \frac{499}{100} = \frac{727-499}{100} = \frac{228}{100} = \frac{57}{25} \)
- \( 0,41 = \frac{41}{100} \)
- \( 3,01 = \frac{301}{100} \)
- \( 0,41 : 3,01 = \frac{41}{100} : \frac{301}{100} = \frac{41}{100} \times \frac{100}{301} = \frac{41}{301} \)
Ответ: а) \( \frac{57}{25} \); б) \( \frac{41}{301} \)
