Answer:
A
Step-by-step explanation:
To convert mixed number as improper fractions, use this rule:
[tex]A\frac{B}C}=\frac{(A*C)+B}{C}[/tex]
For Juan: ([tex]4\frac{1}{6}[/tex])
[tex]4\frac{1}{6}=\frac{(4*6)+1}{6}=\frac{25}{6}[/tex]
For Antonio: ([tex]3\frac{2}{3}[/tex])
[tex]3\frac{2}{3}=\frac{(3*3)+2}{3}=\frac{11}{3}[/tex]
Answer choice A is correct.
