Question

Juan and Ari went to the farmers market to buy fruit. Juan’s bag of apples that he bought weighed 31/7 pounds. Ari’s bag of oranges that she bought weighed 19/3 pounds. About how much heavier is Ari’s bag than Juan’s bag

Answer 1

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.

$\dfrac{31}{7}=\dfrac{31\times 3}{7\times 3} =\dfrac{93}{21}$

Ari’s bag of oranges  weigh 19/3 pounds.

$\dfrac{19}{3}=\dfrac{19\times 7}{3\times 7}=\dfrac{133}{21}$

$\dfrac{133}{21}-\dfrac{93}{21}\\ \\=\dfrac{40}{21}$

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

Answer 2

40/21 pounds orabout 1.9 pounds
