Answer:
Ari's bag is 1.9 pounds heavier than Juan's bag
Step-by-step explanation:
Juan’s bag of apples weigh 31/7 pounds.
[tex]\dfrac{31}{7}=\dfrac{31\times 3}{7\times 3} =\dfrac{93}{21}[/tex]
Ari’s bag of oranges weigh 19/3 pounds.
[tex]\dfrac{19}{3}=\dfrac{19\times 7}{3\times 7}=\dfrac{133}{21}[/tex]
[tex]\dfrac{133}{21}-\dfrac{93}{21}\\ \\=\dfrac{40}{21}[/tex]
Hence, Ari's bag is 40/21 pounds heavier than Juan's bag
i.e. Ari's bag is 1.9 pounds heavier than Juan's bag
