9 = 3/7x
9 x 7/3 = x
9 x 2.333333 = x
21 = x
The whole set is 21.
9
1/9
It is 14/9
9
3/7 x 21 = 9
9/21 is the same as 3/7.
1 and 6/7 or 27/7
If 9 is 3/7 of the entire quantity: 3 --- X = 9 7 So, via cross multiplication: 9 * 7 = 3X 63 = 3X 21 = X The entire set is composed of 21 on units. To check: 3 --- * 21 = 9 ; This statement is true, so 21 is correct. 7
Three sevenths plus six sevenths equals nine sevenths. To add fractions with the same denominator, you simply add the numerators together and keep the denominator the same. In this case, 3 + 6 = 9, so the sum is 9/7.
three sevenths
The number does nothing. It is merely a mathematical concept.
To subtract six sevenths and three fourteenths, first, find a common denominator. The least common multiple of 7 and 14 is 14. Convert six sevenths to four fourteenths (6/7 = 12/14) and then subtract: 12/14 - 3/14 = 9/14. Thus, six sevenths minus three fourteenths equals nine fourteenths, or simplified, is 9/14.
