$8 \frac{2}{5}$ $8 2/5$ or $\frac{42}{5}$ $42/5$

Write 8.4 as a fraction.

The first place to the right of the decimal is the tenths place, so

$8.4 = 8 \frac{4}{10}$ $8.4 = 8 4/10$

Reduce $\frac{4}{10}$ $4/10$ by dividing the numerator and denominator by $2$ $2$

$\frac{4}{10} = \frac{2}{5}$ $4/10 = 2/5$

$8.4 = 8 \frac{4}{10} = 8 \frac{2}{5}$ $8.4 = 8 4/10 = 8 2/5$

$8 \frac{2}{5}$ $8 2/5$ can also be written as an improper fraction.

Multiply the whole number $8$ $8$ by the denominator $5$ $5$ and add the product to the numerator $2$ $2$ .

$8 \cdot 5 = 40$ $8 *5= 40$ then $40 + 2 = 42$ $40 +2 = 42$

$8.4 = 8 \frac{4}{10} = 8 \frac{2}{5} = \frac{42}{5}$ $8.4 = 8 4/10 = 8 2/5= 42/5$
