Answer:
6 cups of flour
Step-by-step explanation:
We can use proportion to solve this problem.
Let x be the amount of flour needed for 15 tablespoons of water.
2 cups = 5 tablespoons
x = 15 tablespoons
cross-multiply
5×x = 15×2
5x =30
Divide both-side of the equation by 5
[tex]\frac{5x}{5}[/tex] = [tex]\frac{30}{5}[/tex]
(On the left-hand side of the equation, 5 at the numerator will cancel-out 5 at the denominator, while on the right-hand side of the equation, 30 will be divided by 5)
x= 6 cups
Therefore 6 cups of flour is needed for 15 tablespoons of water.
