Question

Robbie needs blank teaspoons of black pepper to make four batches since he has 1/3 teaspoons he blank enough black peppers for four batches of soup

Answer 1

Let's begin by listing out the information given to us:

1/2 teaspoon of black pepper makes 4 batches

$\begin{gathered} \frac{1}{2}teaspoon=4batches \\ \end{gathered}$

Can 1/3 teaspoon make 4 batches? This is calculated by:

$\begin{gathered} \frac{1}{2}=4batches \\ \frac{1}{3}=x \\ \text{Cross multiply, we have:} \\ \frac{1}{2}x=\frac{4}{3} \\ x=\frac{4\cdot2}{3}=\frac{8}{3} \\ x=2\frac{2}{3} \end{gathered}$

Therefore, 1/3 teaspoon of black pepper is not enough to make 4 batches
