Question

During a weight loss challenge, Ms. Norris went from 190 pounds to 160 pounds. percent of weight did she lose?

Answer 1

the original weight is 190 pounds

the new weight is 160 pounds

so the percentage of weight loss is

`=\frac{original\text{ weight - new weight}}{\text{original weight}}*100`
`\begin{gathered} =(190-160)/(190)*100 \\ =(30)/(190)*100 \\ =15.78 \end{gathered}`

so she loss 15.78 per cent of the weight.
