  1. multiply 4 and 5 by the same number (2,3,4,5,...)
    which new fractions are given as choices?

    "/" or ":" or "to" all mean the same thing --- a ratio

  3. ok. Start with 4/5
    multiply top and bottom by 2, and you get 4/5 = 4*2 / 5*2 = 8/10
    That's in the list.
    Now just try other values to multiply by.

  4. I'll try
