week review of math

In maths we were learning about turning fractions into percentages. For example, 10 people were on a bus, then 8 people got of. What percent out of 100 is that? What is the fraction of that? The answer is 80% and 8/10. The way you work it out is simple. First you times 10 by 10 and 8 by ten and you have 100 and 80, then you gust make them 80%. To get the fraction you simplify the number in till it is at it's lowest form( for this example, the simplest form will be four fifths (4/5) divide the numerator by 2 and the denominator by 2 ) and then you have your answer.

Thanks D!
