I think it will be 10% because you invited 50 right? And 60 atended or was it 60 and 50 atended? Well either way I think it’s 10%

Answer:

Step-by-step explanation:

To convert mixed number as improper fractions, use this rule:

$A\frac{B}C}=\frac{(A*C)+B}{C}$

<u>For Juan:</u> ( $4\frac{1}{6}$ )

$4\frac{1}{6}=\frac{(4*6)+1}{6}=\frac{25}{6}$

<u>For Antonio:</u> ( $3\frac{2}{3}$ )

$3\frac{2}{3}=\frac{(3*3)+2}{3}=\frac{11}{3}$

Answer choice A is correct.
