Answer 2

$(1 \frac{1}{2} + 2 \frac{2}{3} + 3 \frac{3}{4} ) \div 4 \frac{4}{5} = (2 \frac{1}{2} + 3 \frac{2}{3} + 1 \frac{3}{4} ) \div x$

$( \frac{3}{2} + \frac{8}{3} + \frac{15}{4} ) \div \frac{24}{5} = ( \frac{5}{2} + \frac{11}{3} + \frac{7}{4} ) \div x$

$( \frac{18}{12} + \frac{32}{12} + \frac{45}{12} ) \times \frac{5}{24} = ( \frac{30}{12} + \frac{44}{12} + \frac{21}{12} ) \times\frac{1}{x}$

$\frac{18 + 32 + 45}{12} \times \frac{5}{24} = \frac{30 + 44 + 21}{12} \times \frac{1}{x}$

$\frac{95}{12} \times \frac{5}{24} = \frac{95}{12} \times \frac{1}{x} \: | \div \frac{95}{12}$

$\frac{5}{24} = \frac{1}{x}$

$5x = 24$

$x = \frac{24}{5}$
