what is 80% of 200 in fraction form

First we need to convert the percent to a decimal by dividing it into 100: $${\frac{{\mathtt{80}}}{{\mathtt{100}}}} = {\frac{{\mathtt{4}}}{{\mathtt{5}}}} = {\mathtt{0.8}}$$ Next we multiply that by 100, since "of" means multiplication: $${\frac{{\mathtt{80}}}{{\mathtt{100}}}}{\mathtt{\,\times\,}}{\mathtt{200}} = {\mathtt{160}}$$. If the answer has to be a fraction, put it over 1: $${\frac{{\mathtt{160}}}{{\mathtt{1}}}}$$
