A double recipe of cookies calls for 5 cups of flour.
Which of the following proportions could be used to find the amount of flour for a triple recipe?
5/2= f/3
2/5=f/3
2/3 = f/5
3/2=5/f
To find the amount of flour for a triple recipe, we can set up a proportion using the given information and solve for the unknown variable.
Let's use the proportion: 5/2 = f/3
To solve for f, we can cross-multiply and then solve for f.
Cross-multiplying gives us: 5(3) = 2(f)
Simplifying further: 15 = 2f
To isolate f, we divide both sides of the equation by 2:
15/2 = f
Therefore, the proportion that can be used to find the amount of flour for a triple recipe is 15/2 = f/3.
So, the correct answer is 15/2 = f/3.
