So, adding two rationals is the same as adding two such fractions, which will result in another fraction of this same form since integers are closed under addition and multiplication. Thus, adding two rational numbers produces another rational number.
a/b and c/d are rational numbers with a,b,c,d intergers
so with the same denominators ( equaling a+c over b) or different ones (equaling ab+cb over bd) they end up with the answers of
same denominator= b is not equal to 0
different denominators= d is not equal to 0
this may not make sense but i'm pretty sure i understood you right

Hello!
If a painting is 26 feet long, it's 8 and 2/3 yards long.
This is because there is 3 feet in a yard. You would do 26 divided by 3. You would get 8 yards and have 2 feet left. Obviously 2 feet is smaller than a yard, so it'd be 2/3 of a yard. Therefore the answer is 8 and 2/3 yards.
Hope this helped! :)
Answer:
v = 
Step-by-step explanation:
Given
t = 
( multiply both sides by 4 to clear the fraction )
4t = 3v + 1 ( subtract 1 from both sides )
4t - 1 = 3v ( divide both sides by 3 )
= v
