Answer::
To do percentages with fractions,
divide the numerator by denominator to get a decimal,
so for example, your question, 112/200
112/200 is 0.56 decimal, and then to make it percent,
we multiply by 100,
how does that work?
you move two places to the right because 100 has two zeros
so 0.56 would be 56,
therefore the percent of 112/200 would be 56%
