Is this a serious question? Times the amount by the percent.
Example: 10.00 X 0.50 = 5.00

Percent means "per hundred" so convert percent to a decimal fraction by dividing by 100: 10% = 0.1, 15% = 0.15, etc.

If tipping, say 15% of a check, multiply the check by 0.15. Thus a 15% tip on a $12.59 meal would be $1.8885, or rounded up, $1.89 or $2.00.

I tip about 20% for good service, so for the same $12.59 meal, I would tip either $3.00, which is $2.518 rounded up to the nearest dollar, or $2.50 if rounded down to the nearest ten cents.

To tip fifteen percent, move the decimal one place to the left, then divide that amount by two and add: $1.259 + $0.63 = $1.89, which I would usually round up to $2.00 if leaving a cash tip.

You should be able to do these simple percents in your head, but sometimes I use pencil and paper. If paying both bill and tip by credit card, I like to make the total of bill + tip some even number of dollars. So, for that $12.59 meal, I would first calculate that I need to add 41 cents for the tip to round it up to $13.00 and then add $2.00 for the rest of the tip, bringing the total to $12.59 (meal) + $2.41 (tip) or $15.00 total, which is a little more than a 15% tip but slightly less than 20%.

10% could be 10 cents on a greenback. So a 10% tip on $20.00 could be $2.00. Multiply the % situations the value, 20.00 X 10 = 20000. you're multiplying with the aid of 2 places in 10 as .10 and a pair of places in 20.00. circulate 4 places to the the main suitable option and you have 2.00. Say you spend $35.00 and the tip is 10% in simple terms circulate the decimal element one place to the the main suitable option and you have $3.50.the common tip is 15% or extra and has been for 40 years So a tip on $35.00 could be 3.50 pluss a million/2 this volume , being a million.seventy 5 upload at the same time and there is you tip. $4.seventy 5.

A common tip is 15%.

Take 10% of your bill.

Then add half that amount to make 15%.

For instance, if your bill is $30:

1. Take 10%... that's $3.00.

2. Add half that amount ($1.50) to make a total of $4.50, which equals 15%.

Waiters and waitresses would probably encourage you to tip 20% for excellent service.

In that case, take 10%, then double it.

Or, on a $30 ticket:

1. Take 10% or $3.00.

2. Double it to $6.00.

That'll give you a 20% tip.

Take your bill. Divide by 6. This gives you 16.66%

IE, your bill is $12. You leave a $2 tip. Simple math for you, waitress gets a little extra. Everybody's happy.

Merry Christmas.
