if you mean adding two percents to each other just move the decimal point on both two places to the right, then add them together and multiply the sum by 100
a percent of b = a*b/100 Then add a % sign at the end. For "a is x percent of b": x = 100*a/b
To calculate A dollars increased by B percent, you first find B percent of A by multiplying A by B/100. Then, add this amount to A. The formula can be expressed as: A + (A * B/100), which gives you the total amount after the increase.
A is 23% older than CA=12, whileB=11C=-- To figure out that A is older than we add 12% from A then 11% from B totalling 23%
This depends on the volume of the 40 percent solution you have. The question can be rewritten as: 40%a/(a+b) = 3% where a is the volume of the 40% solution, and b is the volume of water we need to add. Multiply both sides by (a+b) to get: 40%a = 3%a + 3%b Subtract 3%a from both sides to get 37%a = 3%b Divide by 3% to get: 12.3333...a = b Thus whatever the current volume is, you need to add 12.33333 times that volume in water in order to get a 3% solution.
(a% of b) / (b% of a) = [ (0.001a) b ] / [ (0.001b) a ] = 1I'm as surprised as you are !
88 percent is a B 81 to 89 is a B
It is (B/100)*(B/100)*5000 = (B^2)/2
add .65 and .95 your answer will be 1.60 (160%).
To add 60 percent to your total multiply the total by 1.6.
Yes.Recognize that "a percent" means a/100.So this is stating that (a/100) x b = (b/100) x a.Using the distributive property of multiplication, both are (a x b) / 100
111 %. By definition, the percent of any number a in any other number b is 100a/b.
