What’s the decimal 3.5 as a percent%?

350 %    3.5 × 100 and add the % which means ÷ 100

Step-by-step explanation:

To change a decimal to a percent, multiply by 100, then add %

For example, If a store is having a huge 50% off sale, you figure half of anything is .5 of the regular price.

You get that by dividing the denominator 2 into the numerator on a calculator. 1/2 is  1 ÷ 2 = .5  If a batter hits .500, it means getting a hit at half of their at-bats. Same thing.

Take the .500. Multiply by 100. Easily done by moving the decimal 2 places to the right. Now that's 50.0 Drop the useless 0 after the decimal and it's 50%

50/100 is the same as 1/2

Percents greater than 100 are tricky. If someone says "Attendance was up by 350%" It means there were Three and a half times more people than last time they counted.
