6/7, six sevenths
Negative 4 sevenths
There are 2/7 / (1/3) = 2/7 * (3/1) = 6/7 of them.
-1/3 x -6/7 = 1 x 6 = 6 divided by 3 x 7= 21 or 6/21 divide both sides by 3 to reduce it = 2/7 and the sign is positive (SINCE TWO NEGATIVES multiplied = a positive) which kind of makes sense, right, if have 6 of these sevenths, and you want to have one third of them that means 6/2 = 3 or 3 sevenths is a third of six sevenths...
1/2 + 1/3 + 1/3 = 3/6 + 2/6 + 2/6 = 7/6 or 1 1/6
