Divide the number by 100 and then multiply the answer by 5. add the number with the answer.
Add the total of the percentages toegether then divide it by the number of results.
For every whole number, that's 100%, then you divide the first number by the second number (example: 1/2) and then you add any other percentages to get the total percentage.
well, to convert a fraction as a percent divide the top number by the bottom number,then multiply the result by 100and add the percentage sign (%)
Add the two numbers together and then divide by two. Assume the two number is 10 and 20. Add them together (30) and divide by 2 (15).
To get the number one-half of the way between you add the numbers together and divide by 2, leaving you with 5.35
You add together the values and divide by the number of values.
Divide it by 5, then add a hundredth of the original number, e.g. 21% of 345 would be 69 + 3.45 = 72.45
3, looks as if you add 9 to the first number, then add 1, divide by 5, add 9, add 1, divide by 5 to get 3
Half is the same thing as .5 so you divide 30 by .5 and you get 60 then you add 10 so it is 70. TADA!!!
You add the numbers. Then you divide by the number of numbers (i.e., if you have three numbers, you divide the sum by 3).You add the numbers. Then you divide by the number of numbers (i.e., if you have three numbers, you divide the sum by 3).You add the numbers. Then you divide by the number of numbers (i.e., if you have three numbers, you divide the sum by 3).You add the numbers. Then you divide by the number of numbers (i.e., if you have three numbers, you divide the sum by 3).
5/8 add both fractions up then divide by 2
12.5? or "what". Did you mean "Divide thirty by half and add ten?"? Then the answer would be seventy.
Divide the bottom number into the top number. For example 1/2. Divide 1 by 2=.50, then multiply by 100 and add a percent sign, i.e., 0.50 x 100 = 50%
Add the three together and divide by three.
Multiply the percent times the dollar amount, then divide by 100. Add that amount to the dollar amount. For example: Add 15% to $1500. Multiply 15x1500 to get 22500. Then divide by 100 to get 225. Add the 225 to 1500 to get $1725.
4,500,000,000,000,000,000. An easier way is to just divide 90 by 2 and then add all the zeros.
The answer is 70 (30 / 0.5 = 60, 60 + 10 = 70)
The answer is 90. Dividing in half is also same as multiplying it by 2. Then you add 10, you'll get 90.
First you take your wingspan in inches, which is usually your hight. Next you divide that number by 2. Then you divide it by 2, because only half your arm is taller than you. Then you add that number to your height and that is how high you can touch standing.
To add 20 percent to a number, multiply the number by 1.2. For example, adding 20 percent to 50 gives 50 x 1.2 = 60.
