#### Explanation:

Set up a ratio

The percentage of candy bars left is $100 - 70 = 30$

Let 30% be the partial percentage.
Let 100% be the total percentage.
Let x be the partial number of candy bars.
Let 20 be the total number of candy bars.

$\frac{30}{100} = \frac{x}{20}$ Multiply both sides by 20

$\frac{30 \times 20}{100} = \frac{x \times 20}{20}$ This leaves

$\frac{600}{100} = x$ Dividing by 100 gives

$6 = x$
.
There are 6 candy bars left
