Note: this class is part of a program that generates 10 fraction math problems (1 fraction +, -, /, or * another fraction)
an object problems is created and methods are used to return the question and  answer.

class Problems {

	public Problems()
	{
		//generates first array of fractions
		int[][] fractionGroup1 = new int[2][10];

		for (int r=0;r<2;r++)
		{
			for (int c=0;c<fractionGroup1[r].length;c++)
			{
				fractionGroup1[r][c] = ( (int) (Math.random() * 9) + 1 );
			}
		}


................
//returns numerator of 1st number
	public int getNumerator1(int problemNum)
	{
		return fractionGroup1[0][problemNum];
