how many cups are equivalent to 4 tablespoons of sugar?

Explanation:

Step1: Identify the conversion ratio

From the number - line, 8 tablespoons is equivalent to $\frac{1}{4}$ cup.

Step2: Set up a proportion

Let $x$ be the number of cups equivalent to 4 tablespoons. The proportion is $\frac{x}{4}=\frac{\frac{1}{4}}{8}$.

Step3: Cross - multiply and solve

Cross - multiplying gives $8x = 4\times\frac{1}{4}$. Simplifying the right - hand side, $4\times\frac{1}{4}=1$. Then, $x=\frac{1}{8}$.

Answer:

$\frac{1}{8}$
