Answer:
B. 4 tablespoons
Step-by-step explanation:
Let’s make a proportion using the following setup:
tablespoons/servings=tablespoons/servings
We know that 12 tablespoons are needed for 60 servings.
12/60=tablespoons/servings
We don’t know how many tablespoons are needed for 20 servings. We can say x tablespoons make 20 servings.
12/60=x/20
Want want to solve for x, so we must isolate x. x is being divided by 20. The inverse of division is multiplication. Multiply both sides of the proportion by 20.
20*(12/60)=(x/20)*20
20*12/60=x
20*0.2=x
4=x
x= 4 tablespoons
4 tablespoons of butter are used to make 20 servings.
