How would you calculate this?

Question

We have a diet contest going on at work and they're doing it by percentage lost not lbs lost. How would you calculate the percentage lost?

Answer 1

that the weight you lose and divide it by the original weight. then multiply that number by 100.

say you weigh 170 originally and you lost 8 pounds.

8 divided by 170=.047

.047x100=4.7%

Answer 2

Percentage lost = (old weight - new weight) / old weight

For example, if you weighed 120 to start with, and you weighed 115 afterwards, your percentage lost would be (120 - 115) / 120 = 5/120 = 4.166667%

But someone who lost 5 pounds and started at 150 would have a percentage lost of 5/150 = 3.33333%

Answer 3

Step on a scale and measure you own weight. Divide the wight by 100. This value would represent 1%.

Example: if your weight is 150 pounds, divide by 100 is 1.5 pounds or 1%. Whatever your weight loss may be, divide that number by the 1% value for total weight loss in percent.

Answer 4

Multiply the weight lost by 100, then divide it by the original weight.

For example 125lbs to start with, losing 10lbs:

10 * 100 / 125 = 8% weight lost

Answer 5

Percentage lost= (lbs lose)/(original total lbs) * 100 %

from 100lbs down to 80 lbs:

lbs lose : 20 lbs

percentage lose= 20 lbs / (100 lbs ) *100% = 20%

from 50lbs down to 30 lbs

lbs lose : 20 lbs

percentage lose= 20 lbs / (50 lbs ) *100% = 40%
