I need help on 3,4,5,6

1. Explain why, for any positive whole number n, ,+ is smaller than , . Reason from the meaning of fractions (parts and wholes), don't do any algebraic manipulations. 2. A student has a conjecture. Given a proper fraction, if you add the same number to the numerator and denominator then you get an equivalent fraction. Is the student's conjecture true? Justify your answer. 3. Without solving them, say whether the equations below have a positive solution, a negative solution, a zero solution, or no solution. Give a reason for your answer. Example: 2x + 4 = 5. We are adding a number, 2x, to 4 to get 5. Thus, 2x must be positive. Since 2 is positive, in order for the product 2x to be positive, then x must also be positive. a. 4 - 2x = 5 b. 5x = 2 C. 4= 5+x2 4. What number is halfway between 3.3 and 3.32? 5. Which of the following is/ are equivalent to -? Select all that apply. A. vil W X x B. UILH x 3x C. uil X X 3 D. + uil x 1 1 E. zx+ Ex + zx F. x txtx 5 6. Solve with a picture. You have three cookies and you want to divide them fairly among five people. How much would each person get
