Answer 1

Joel read the most out of the group.

Answer 2

Answer with explanation:

It is given that,

⇒  Armando read 15% of his 46-page book.

Number of pages read by Armando in a day

                    $=\frac{15}{100} \times 46\\\\=\frac{690}{100}\\\\=6.9$  

⇒  Billy read 11% of his 72-page book.

   Number of pages read by Billy in a day

                    $=\frac{11}{100} \times 72\\\\=\frac{792}{100}\\\\=7.92$  

⇒   Robert read 12% of his 68-page book.  

         Number of pages read by Robert in a day

                    $=\frac{12}{100} \times 68\\\\=\frac{816}{100}\\\\=8.16$  

⇒     Joel read 14% of his 69-page book.

        Number of pages read by Joel in a day

                    $=\frac{14}{100} \times 69\\\\=\frac{966}{100}\\\\=9.66$

⇒ Joel  read the greatest number of pages in a day.
