A recipe needs 2 cups of flour for 12 cookies. How many cups are needed for 30 cookies?
a.4 cups
b.2.5 cups
c.6 cups
d.5 cups
Explicación
Set up a proportion: 2/12 = x/30, so x = (2 × 30)/12 = 5 cups. Proportions keep the ratio of flour to cookies constant. Scaling recipes uses this direct relationship.
