7) According to an ancient belief, when a friend visits a sick person, 1/70 of his sickness is taken away. What is the least amount of friends that need to visit to take away at least 81% of a person's illness?
can any one get the answer
56.7(round that up to 57 to be realistic) because if you represent it as a math equation it looks like this:
1/70 times X=81/100(what 81% is as a fraction)
then if you solve for x, you get 56.7
