6/8 is also equal to 3/4. So the decimal would be .75 and the percentage would be 75%.
To find a decimal of a fraction, you have to take the numerator (6) and divide by the denominator (8). I got the answer 0.75, and your probably thinking no its not. Thats three fourths. Well 6/8 is simplified to 3/4. I learned this in fifth grade. Hope this helped
