Question

(15,25-3 5/12+2 2/9 - 2,5):(6 1/5- 4 1/3)

Answer 1

$(15.25 - 3 \frac{5}{12} + 2 \frac{2}{9} - 2.5) \div (6 \frac{1}{5} - 4 \frac{1}{3} ) = ( \frac{61}{4} - \frac{41}{12} + \frac{20}{9} - \frac{5}{2} ) \div ( \frac{31}{5} - \frac{13}{3} ) = \frac{104}{9} \div \frac{28}{15} = \frac{104}{9} \times \frac{15}{28} = \frac{26}{3} \times \frac{5}{7} = \frac{130}{21} = 6 \frac{4}{21}$
