2 1/3 + 1 6/7 first needs to be converted to the least common factor of the denominator, so the least common factor of 3 and 7 is 21. then you would multiply the top and the bottom by the number that multiplies with the denominator to get 21. The number to multiply to 3 would be multiplied by 7 to get 21 and vise versa, so for 2 1/3, 1 x 7 = 7 and 3 x 7 = 21 which makes 2 7/21. For 1 6/7, 6 x 3 = 18 and 7 x 3 = 21 which makes 1 18/21. 2 7/21 + 1 18/21 = 4 4/21 or, in improper form, 88/21
6/7, six sevenths
two and two sevenths plus six and five sixths is 52.
11/21 (eleven over twenty-one)
1 46/70
-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...
Ten sevenths or one and three sevenths
Well, isn't that a happy little math problem we have here! To find one third of six sevenths, we can first simplify six sevenths to two thirds. Then, we can take one third of two thirds, which equals two ninths. Just remember, there are no mistakes in math, only happy little accidents!
6/7, six sevenths
8.523809524 or 179/21 or 8 and 11/21
two and two sevenths plus six and five sixths is 52.
I don't know. That is why I'm asking.
11/21 (eleven over twenty-one)
Well, firstly, the LCM (Lowest Common Multiple) of 3 and 7 is 21. Try to convert those fractions into fractions with denominators of 21. Multiply 3x7 in one thirds and 1x7, which changes one third to seven twenty-oneths. Multiply 7x3 in two sevenths and 2x3, which changes two sevenths to six twenty-oneths. Therefore, one third (seven twenty-oneths) is greater than two sevenths (six twenty-oneths).
6/7
It is 10/21.
Expressed as a mixed number in its simplest form, 3/7 + 6/7 = 1 2/7 or one and two sevenths.
12/14 + 7/14 = 19/14
