First we need to make it a decimal. So we need the denominator to be 10, 100, 1000, 10000 or something along those guidelines. * can't go in 10, 100 but it can go in the thousandths place ( 1000 / 8 = 125 ) So we multiple the top and the bottom of 6 2/8 by 125. our fraction now looks like this 6 375/1000 In a decimal it looks like 6.375. To make it a percent, move the decimal two places to the right. The percent is 637.5% and the decimal is 6.375. Hope that helps!
