Answer:36/5.
Explanation:
To double the pizza recipe, Rain needs to double the amount of flour required in the original recipe.
The original recipe calls for 3 3/5 cups of flour. To double this amount, we can multiply it by 2.
To multiply a mixed number by a whole number, we first convert the mixed number to an improper fraction.
In this case, 3 3/5 can be written as (5 * 3 + 3) / 5 = 18/5.
Next, we multiply the improper fraction by 2:
18/5 * 2 = (18 * 2) / 5 = 36/5.
So, Rain will need 36/5 cups of flour for the doubled pizza recipe.
To simplify the fraction, we can divide both the numerator and the denominator by their greatest common divisor, which is 1 in this case:
36/5 ÷ 1/1 = (36/5) * (1/1) = 36/5.
Therefore, Rain will need 36/5 cups of flour for the doubled pizza recipe.
