Answer 1

Let RN be x

$\\ \sf\longmapsto \dfrac{10}{x}=\dfrac{8}{5}$

$\\ \sf\longmapsto 8x=50$

$\\ \sf\longmapsto x=\dfrac{50}{8}$

$\\ \sf\longmapsto x=6.2$

Answer 2

Step-by-step explanation:

${ \tt{ \frac{(10 +RN) }{10} = \frac{(8 + 5)}{8} }} \\ \\ { \tt{{10 +RN } = \frac{(8 + 5) \times 10}{8} }} \\ \\ { \tt{10 + RN = 16.25}} \\ \\ { \tt{RN = 6.25}}$
