the graphs have fractions on the y axis
the best graph to use to represent fractions is a pie graph, that is if all the fractions denominators are the same...
You cannot solve fractions. There may be sums or products containing fractions or equations that can be solved. But fractions themselves cannot.
Yes.
You cannot solve proper fractions. You may be able to solve problems involving fractions but that is NOT the same thing. Furthermore, the solution methods depend on the problem.
Line graph
The slope is defined as rise/run or y/x. To solve it, you use 2 coordinates from that graph and use the formula m=X1/X2 - Y1/Y2.
You cannot solve a fraction. You can solve a question about fractions, you can carry out basic operations with fractions, convert them from one form to another but none of these is "solving" them.
Not necessarily, but often it is simpler to convert fractions into decimals to solve the equation.
One can solve equations of motion by graph by taking readings of the point of interception.
You solve it just like they are proper fractions
That depends what kind of calculation you want to do with the fractions.
You can eliminate the fractions before proceeding to solve the equation to allow for easy factorization.
