[tex] \rm \frac{96}{45} = \frac{b}{20} [/tex]
[tex] \rm (\frac{96}{45} \div \frac{3}{3} ) = \frac{b}{20} [/tex]
[tex] \rm \frac{32}{15} = \frac{b}{20} [/tex]
[tex] \rm 32 \times 20 = 15 \times b [/tex]
[tex] \rm 640 = 15b [/tex]
[tex] \rm \frac{640}{15} = b [/tex]
[tex] \rm \frac{128}{3} = b [/tex]
[tex] \rm 42 \frac{2}{3} = b [/tex]
[tex] \pink{\boxed{\rm 42,6 = b}} [/tex]
