Katherine Johnson divided a report into five equal sections and used $\frac{2}{5}$ of it for a summary. What fraction of the report remained?

Matching: Match each scenario to the equivalent simplified fraction.

Left: A. Hedy tested 2 of 10 prototype circuits. B. An inventor used 1 of 3 sections of a notebook for notes. C. A scientist used 4 of 8 data charts in a display.

Right:

$\frac{1}{2}$
$\frac{1}{5}$
$\frac{1}{3}$

Correct pairs: A → 2 ($\frac{2}{10} = \frac{1}{5}$), B → 3 ($\frac{1}{3}$), C → 1 ($\frac{4}{8} = \frac{1}{2}$).
