  1. I’m not positive, but this is what my class came up with:

    Largest: 9.64 * 8.75 = 84.35
    Lowest: 1.35 * 2.46 = 3.321

  2. The smallest: 1.35 times 2.46

  3. Same answer for the least.

  4. well i was close 1.36 X 2.45

    REAL QUODENT 1.35 X 2.46

    i was so close OwO”.

  5. well i was close 1.36 X 2.45

    REAL QUODENT 1.35 X 2.46

    i was super close OwO”.

  6. I think that the largest is 9.76 x 8.65

    I can confirm that these are the solutions:

    Smallest possible result:
    3.321 = 2.46 *1.35

    Greatest possible result:
    84.35 = 9.64 *8.75
