## Related Questions   Multiply by 1.38. -- answer -- If X = 100 percent then X times 1.38 = 138% So, if the number to be increased were to be 50, then 50 times 1.38 = 69  50% of a number, X, is 0.50X 54% of a number,X, is 0.54X .54X/.50 X = 1.08 = 8% increase   Find the difference between the first number and the second number and divide by the first number then change to a percent. 50-40=10 10/40=.25 or 25 percent increase. Don't forget to divide by the beginning amount because 50 to 40 is different.   Multiply the number you are increasing by 0.5    If you have a number, for example, 100, and add 50 percent, this is equal to 100 + 50 = 150.If you then increase the number 150 by 50 percent, you will get 150 + 75 = 225.Therefore, this is not the same as doubling.by ayaz khan 6% of 50 = 3 so, 50 increased by 6% is 53 That's a 20% increase in price. pervent increase = (new amount - old amount)/old amount = (60 - 50)/50 = 10/50 = 1/5 = 20%   The circumference is directly proportional to the radius. So increasing the radius by 50% causes the circumference to also increase by 50%.  10% of 500 = 50 30% = 50 x 3 =150 Now to increase 500 by 30%: 500 + 150 = 650 If 47 increases to 97, it increases by 50 units. For 47 units, the increase is 50 units For 1 unit, the increase is 50/47 units For 100 units, the increase is (50/47)(100) = 106.38 % Percent of increase is the product of changes in price over the original price with 100%. That is:percent increase = (changes in price/original price) x 100%.For example:In a year period, the price of a stock increased from 50 dollars a share to 59 dollars a share. To find the percent of increase in the share price, compare the change in price to the original price:percent increase = (changes in price/original price) x 100%.= (59 dollars - 50 dollars)/50 dollars x 100%= 18% the percentage increase is 50%
