Question

A muffin recipe calls for 2/5 tablespoons of vanilla extract to make 6 muffins. Arthur is making 18 muffins How much vanilla extract does he need?

Answer 1

Im gonna go and guess that 2/5 means two and a half (2.5 or 2,5 I always forget that :D)

Anyway:

2.5 tbsp = 6 muffins
3*2.5 tbsp = 3*6 muffins
7.5 tbsp = 18 muffins
