How to convert integer to decimal format in Java (Android Studio)?

I am trying to convert my two answers text1 and text2 into a decimal format. How is this possible?

    int number1, number2, answer, answer2;
    EditText edit1 = (EditText)findViewById(R.id.aNum);
    EditText edit2 = (EditText)findViewById(R.id.bNum);
    TextView text1 = (TextView)findViewById(R.id.answerNum);
    TextView text2 = (TextView)findViewById(R.id.answerNum2);
    number1 = Integer.parseInt(edit1.getText().toString());
    number2 = Integer.parseInt(edit2.getText().toString());
    answer = (number2 / (number1 * 1000)) * 60;
    answer2 = answer/60;
    text1.setText(Integer.toString(answer));
    text2.setText(Integer.toString(answer2));
