Answer:
Amayeta ran the most miles.
Step-by-step explanation:
first,I solved for Lindsey. I found a common denominator of 45, and made each fraction have a denominator of 45. I ended up with 8 35/45 + (-4 36/45) after I subtracted I got 3 44/45.
then I solved for Andrew. I found a common denominator of 30. I made each fraction have a denominator of 30. I ended up with 175/30-64/30. after I subtracted I ended up with 111/30, or 3 7/10.
then I solved for Amayeta. I found a common denominator of 90, and made each fraction have a denominator of 90. I ended up with 315/90+34/90. after I subtracted I got 359/90, or 3 89/90.
finally, I had to compare each fraction. all three answers had a common denominator of 90. so, I changed each fraction to have a denominator of 90. I ended up with 3 88/90, 3 63/90, and 3 89/90. The last one, which was equal to the sum of Amayeta, was the biggest, therefore showing that Amayeta ran the most miles.
