Answer:
[tex]1\dfrac{17}{19}[/tex]
Step-by-step explanation:
19 bananas =1 watermelon
3 pineapples =1 watermelon
Then
19 bananas = 3 pineapples
1 pineapple = 3 grapes,
then
3 pineapples = 9 grapes
3 pineapples = 9 grapes
19 bananas = 3 pineapples
then
9 grapes = 19 bananas
9 grapes = 19 bananas
x grapes = 4 bananas
Write a proportion:
[tex]\dfrac{9}{x}=\dfrac{19}{4}[/tex]
Cross multiply
[tex]19x=9\cdot 4\\ \\19x=36\\ \\x=\dfrac{36}{19}=1\dfrac{17}{19}[/tex]
