Each and every rational number except 0. Once you leave the domain of integers, all rational numbers (excluding 0) divide into every other rational number with a quotient that is rational.
The above can be extended to real numbers.
20 of course !
6 and 2 sevenths
2 and four sevenths 5 & 2/7 minus 2 & 5/7 equals 2 & 4/7
3 and 2/7
3 - (2/7) = 2 5/7 or two and five sevenths.
5 2/7 already is a rational number - you don't need to convert anything.
Oh, dude, you're hitting me with some math here. So, like, to find a fraction equivalent to five sevenths, you just gotta multiply or divide the numerator and denominator by the same number. In this case, if you multiply both by 2, you get 10/14, which is equivalent to five sevenths. Math, man, it's a wild ride.
35 sixths 5/3 x 2/7 =35 6ths
1 2/7
Five multiplied by 4/7 is 2 6/7
2 and 1/7
A ratio of 2:5 implies seven equal parts. Therefore, the 2 represents 2/7, or two sevenths, and the 5 represents 5/7, or five sevenths.
