    Answer: 4/8 = 0.5 and 9/10= 0.9. If you subtract 0.9 by 0.5, you end up with 0.4. I would say not reasonable.

    Answer:

    No, it is not reasonable

    Step-by-step explanation:

    Writing 9/10 and 4/8 as fractions out of 100, and then as decimals

    9/10 = 90/100 = 0.9

    4/8 = 1/2 = 50/100 = 0.5

    0.9 – 0.5 = 0.4

    Not 0, like Kevin estimated
