Question

3 grapes= 1 pineapple

Answer 1

Answer:

$1\dfrac{17}{19}$

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:

$\dfrac{9}{x}=\dfrac{19}{4}$

Cross multiply

$19x=9\cdot 4\\ \\19x=36\\ \\x=\dfrac{36}{19}=1\dfrac{17}{19}$
