How do I fix this to make the loop questions true?

Create a program that prompts the user for a number of modulus math questions that they want to answer. The program will then quiz the player on that number of randomly generated questions of the style:

(random 1-300) % (random 2-7) = ?

For each question the user gets correct they earn a point. After ALL the questions have been asked, the program will display the number of correct answers as well as the percentage of correct answers.

  1.   System.out.println("Q#" + mcq + ")" + (int)(300*Math.random()+1) +  " % "   + (int)(7*Math.random()+2));
  2.             System.out.print("What is your answer: ");
  3.             answer = input.nextInt();
  4.             if(answer==(int)(300*Math.random()+1)  %  (int)(7*Math.random()+2)){
  5.                 System.out.println("Correct!");
  6.                 points++;
  7.             } else{
  8.                 System.out.println("Wrong!");
  9.             }

One issue that looks obvious is whenever you call random() function ,it will generate a random number. Now on line #1 lets say numerator & denominator evaluate to  100 & 3 whats the gaurantee that line#4 random will generate the same numberator & denominator ??

Please assign the numerator & denominator only once when you compute with with random function.Then use the modulo to on the captured numerator & denominator, as the prob statement requires .
