Just multiply the numerator and the denominator by the same number. For example, 6 x 2 equals 12 and 7 x 2 equals 14. That's how I got 12/14 as one of the fractions that equal 6/7. When reduced by the number you multiplied 6 and 7 by, you will get 6/7. You can multiply any number by 6/7. Hope this helps!
