Answer 2

Answer:

$30\% \times x = 40\% \times y \\ \frac{3\cancel0}{10\cancel0} \times x = \frac{\cancel{40}_{ \: \: 2}}{\cancel{100}_{ \: \: 5}} \times y \\ \frac{3}{10} x = \frac{2}{5} y \\ \frac{3x}{10} = \frac{2y}{5} \\ 3x \times 5 = 2y \times 10 \\ 15x = 20y \\ \frac{x}{y} = \frac{\cancel{20}_{ \: \: 4} }{\cancel{15}_{ \: \: 3}} \\ \boxed{ \frac{x}{y} = \underline{ \underline{\frac{4}{3} }}} \\ \\ Here, \\ x = 4, \: \: \: y = 3 \\ \\ 30\% \times x = 40\% \times y \\ \frac{3}{10} \times x = \frac{2}{5} \times y \\ \frac{3}{10} \times 4 = \frac{2}{5} \times 3 \\ \frac{ \cancel{12}_{ \: \: 6}}{ \cancel{10}_{ \: \: 5}} = \frac{6}{5} \\ \boxed{ \underline{ \underline{ \frac{6}{5} = \frac{6}{5} }}}$
