Question

Find the value of x ​

Answer 1

$\frac{2 \frac{1}{2} }{x} = \frac{ 3\frac{1}{2} }{4} \\ \\ \frac{ \frac{5}{2} }{x} = \frac{ \frac{7}{2} }{4} \\ \\ \frac{5}{2 \times x} = \frac{7}{2 \times 4} \\ \\ \frac{5}{2x} = \frac{7}{8} \\ \\ 5 \times 8 = 7 \times 2x \\ \\ \frac{5 \times 8}{7 \times 2} = x \\ \\ x = \frac{20}{7}$
