Options A and E are correct.
A. 4/5 x 5/6
E. 6/7 x 7/9
Let us simplify the expressions one after the other to identify the ones with a product of 2/3
[tex]\frac{4}{5} \times \frac{5}{6} = \frac{4}{6} = \frac{2}{3}[/tex]
[tex]\frac{7}{8} \times \frac{9}{10} = \frac{63}{80}[/tex]
[tex]\frac{1}{3} \times \frac{2}{3} = \frac{2}{9}[/tex]
[tex]\frac{3}{4} \times \frac{7}{12} = \frac{7}{16}[/tex]
[tex]\frac{6}{7} \times \frac{7}{9} = \frac{6}{9} = \frac{2}{3}[/tex]
From the options considered, only options A and E give 2/3 as a product
