Answer:
[tex]\frac{b}{6}[/tex]
Step-by-step explanation:
leave first fraction, change ÷ to × , turn 4 'upside down'
[tex]\frac{2b}{3}[/tex] ÷ 4
= [tex]\frac{2b}{3}[/tex] × [tex]\frac{1}{4}[/tex] ( cancel 2 and 4 by 2 )
= [tex]\frac{b}{3}[/tex] × [tex]\frac{1}{2}[/tex]
= [tex]\frac{b}{2(3)}[/tex]
= [tex]\frac{b}{6}[/tex]
