<h2>3x + y = 1</h2>
Step-by-step explanation:

To convert from decimal to percent, just multiply the decimal value by 100. In this example we have: 0.768 × 100 = 76.8%
The ease way:
1) Move the decimal point two places to the right: 0.768 → 7.68 → 76.8.
2) Add a % sign: 76.8%
"<u>Answer: 76.8%"</u>
