## Solution 12311: Performing Decimal, Fraction and Percent Conversions on the TI-36X Solar and TI-36X II.

### How do I perform decimal, fraction, and percent conversions using the TI-36X Solar and TI-36X II?

The following examples will demonstrate how to perform decimal, fraction, and percent conversions using the TI-36X Solar and TI-36X II:

Example: Convert 1/5 to a decimal.

Solution:
• If using the TI-36X Solar, press  [a b/c]  to input the fraction. If using the TI-36X II, press  [A b/c]  to input the fraction.
• If using the TI-36X Solar, press [3rd] [F<>D] to convert the fraction to a decimal.
• If using the TI-36X II, press [2nd] [F<>D] to convert the fraction to a decimal.
The screen will show 0.2

Example: Convert 1/4 to a percent.

Solution:
• If using the TI-36X Solar, press  [a b/c]  to input the fraction. If using the TI-36X II, press  [A b/c]  to input the fraction.
• Multiply the results by 100.
The screen will show 25, which is the percentage.

Example: 16 is what % of 90

Solution:
• This problem can be re-written mathematically as 90 * __  = 16. To find the results, divide 16 by 90, then multiply the results by 100.
• Input 16 [÷] 90 [X] 100 [=]
The screen will show 17.77777778
