100 Centimeters = 1 Meteror mutliply it by 100Multiply by 100 : so 1 meter is 100 cm, 100 meters is 100000 cm etc.
First find the percentage of a number:a/b = p/100, *P is the percentageHere is a sample problem:What is %40 of 50?You would write that as:a/50 = 40/100Simplify (When possible)a/50 = 2/5Convert:How many times does it take 5 to go into 50?a/50 = 2x10/5x10Answer: 10a/50 = 20/50Divide (by 50)a = 2020 is %40 of 50Then find increase or decrease:Sample problem: 100 to 50 (decrease) *remember: a/b = p/100We are trying to find p so the equation is:50/100 = p/100Multiply by 100 to get p by itself50 = pAnswer: The percentage of decrease is 50 percentSample problem: 256 to 224 (decrease) *remember: a/b = p/100We are trying to find p so the equation is:224/256 = p/100Simplify (When possible).875 = p/100Multiply by 100 to get p by itself87.5 = pAnswer: The percentage of decrease is 87.5 percent
6 - 6 + 6 - 6 + 6 - (6 / 6) = 5
(6/6)+(6/6)+(6/6)+6=9
(6-6)*6/6 = 6-6
((6+6)/6)^6 = (12/6)^6 = 2^6 =64
0.05 = 5 (1/150) + 1/xWrite the left side as a fraction:5/100 = 5/150 + 1/xMultiply each side by 'x':5x/100 = 5x/150 + 1Multiply each side by 100:5x = 500x/150 + 100Multiply each side by 150:750x = 500x + 15,000Subtract 500x from each side:250x = 15,000Divide each side by 250:x = 60
Percentages can always by divided by 100 to get their decimal value. 1% = 1/100Multiply the decimal (in this case fraction) value by 89 to get your answer:(1/100) x 89 = 89/100 = 0.89Additional explanation:100% is everything (in this case 89)If you divide this in 100 equal pieces you get 100 pieces each worth 1%.So 89/100 =0.89(If you need 25% that's no problem either. That is he same as a quarter89/4 = 89*0.25 = 22.25)Just remember that percent means per 100 parts.
Since a percentage is just a way to express a number as a portion of 100, set up an equation. The percentage over 100 needs to equal the increase over the original number.Let's say the price of gas increased from $2 to $3. The increase is 3 - 2 = 1. Put the increase over the original number and let x=the percentage:1/2 = x/100Multiply both sides of the equation by 100 to get xalone.100/2 = x100/2 = 50 = x, so the price of gas increased by 50%.
6 + 6 - 6 * 6 - 6 = 6 + 6 - 36 - 6 = -30
6+6+6+6+6+6+6+6+6 =54 This can also be written as 6*9. That is because 6 is added 9 times.
((6+6)/6)^6 = (12/6)^6 = 2^6 =64
