If you weigh 54.4 kilograms and have 3.3 pounds of intestinal bacteria what percentage of your body weight is intestinal bacteria?

first you need to convert your units (your weight is in Kilograms and the bacteria is in pounds)

if you convert to pounds (then multiply the 54.4 kilograms times 2.2) then you weight is about 120 pounds (this is rounded).

to find percentage of bacteria, divide 3.3 pounds by 120 pounds and multiply by 100 [(3.3/120) x 100] = 2.75%

so 2.75 percent of your body weight is intestinal bacteria
