Explanation:
To find out how far Bryce hiked, we need to multiply Chloe and Dominic's distance by 2 3/4. To do this, we'll first convert 2 3/4 to an improper fraction:
2 3/4 = (2 x 4 + 3)/4 = 11/4
Now we can multiply 9 1/11 by 11/4:
9 1/11 x 11/4 = (99/11) x (11/4)
= 99/4
= 24 3/4
Therefore, Bryce hiked 24 3/4 miles, which is 2 3/4 times as far as Chloe and Dominic hiked.
