Verified answer

$\frac{7}{8} :y=2\; \; \to \; \; y= \frac{7}{8\cdot 2} =\frac{7}{16}\\\\4x= \frac{16}{25} \; \; \to \; \; x= \frac{16}{25\cdot 4}=\frac{4}{25}\\\\y:9= \frac{5}{12} \; \; \to \; \; y= \frac{5\cdot 9}{12} = \frac{15}{4}=3,75\\\\11x= \frac{4}{5} \; \; \to \; \; x=\frac{4}{5\cdot 11}= \frac{4}{55}$
