Question 699577
since she has lost 32% of her body weight, she has 68% of it left!
This 68% is equal to 57.8kg.
Now we want to find out what 1% of her body weight is.
if we divide by 68 we will find 1%.
{{{(57.8/68) = 0.85}}}
Since this is 1%, if we multiply by 100 we will find 100%!
{{{0.85*100 = 85}}}
So Ben originally weighed 85kg.
