Weight Loss Percentage worksheet

1. Percent of starting weight lost: 5%

1. Weight lost is the starting weight minus the current weight

   $200\text{\hspace{0.17em}kg}-190\text{\hspace{0.17em}kg}$$=10\text{\hspace{0.17em}kg}$

2. Divide by the starting weight and multiply by 100 to express it as a percentage

   $\frac{10}{200}\times 100$$=\mathrm{5\%}$

2. Percent of starting weight lost: 14.12%

1. Weight lost is the starting weight minus the current weight

   $170\text{\hspace{0.17em}kg}-146\text{\hspace{0.17em}kg}$$=24\text{\hspace{0.17em}kg}$

2. Divide by the starting weight and multiply by 100 to express it as a percentage

   $\frac{24}{170}\times 100$$=\mathrm{14.117647\%}$

   $\frac{20}{180}\times 100$$=\mathrm{11.111111\%}$

6. Percent of starting weight lost: -37.5%

1. Weight lost is the starting weight minus the current weight

   $160\text{\hspace{0.17em}lb}-220\text{\hspace{0.17em}lb}$$=\mathrm{-60}\text{\hspace{0.17em}lb}$

2. Divide by the starting weight and multiply by 100 to express it as a percentage

   $\frac{\mathrm{-60}}{160}\times 100$$=\mathrm{-37.5\%}$

1. Weight lost is the starting weight minus the current weight

   $275\text{\hspace{0.17em}lb}-270\text{\hspace{0.17em}lb}$$=5\text{\hspace{0.17em}lb}$

2. Divide by the starting weight and multiply by 100 to express it as a percentage

   $\frac{5}{275}\times 100$$=\mathrm{1.818182\%}$

8. Percent of starting weight lost: 16.67%

1. Weight lost is the starting weight minus the current weight

   $240\text{\hspace{0.17em}lb}-200\text{\hspace{0.17em}lb}$$=40\text{\hspace{0.17em}lb}$
