65 is what percentage of 130? Please explain your work so i can know how to do this.
Think of the question as a fraction (that is, 65/130) then, see "Change a fraction into a percent:" http://www.wikihow.com/Convert-Percents,-Fractions,-and-DecimalsHere's another way of thinking about it: http://www.mathgoodies.com/lessons/vol4/fractions_to_percents.htmlOne more way: http://www.dummies.com/how-to/content/how-to-convert-fractions-into-percents.htmlUse the way that makes the most sense to you.
50% its half of 130 or you could do 65 divided by 130 equals .5 times 100
10 percent of 130 is 13 5 percent of 130 is 6.5 so 50percent of 130 is 65 add THEM all up so it's 13+6.5+65=84.5
