Answer:
[tex]\frac{1}{6}[/tex]
Step-by-step explanation:
[tex]\frac{7}{9}[/tex] × [tex]\frac{3}{4}[/tex] × [tex]\frac{2}{7}[/tex]
the 7 on the numerator/ denominator cancel to 1
the 3 and 9 cancel ( 3 → 1 and 9 → 3 )
the 2 and 4 cancel ( 2 → 1 and 4 → 2 )
= [tex]\frac{1}{3}[/tex] × [tex]\frac{1}{2}[/tex] × [tex]\frac{1}{1}[/tex]
multiply the remaining values on the numerators/ denominators
= [tex]\frac{1(1)(1)}{3(2)(1)}[/tex] = [tex]\frac{1}{6}[/tex]
