    1. .25
    2. .6
    3. .05
    4. .5
    5. .75
    6. .08
    1. Possible response: 6/8 = 3/4 and 3/4 = 75/100, this is .75 as a decimal.
    1. 17/25
    2. 1/20
    3. 8/25
    4. 4/25
    5. 2/5
    6. 1/2
    1. Possible response: I started with 32/100. I know both 32 and 100 are divisible by 4, so 32/100 = 8/25. There is no number that can divide into both 8 and 25 evenly, so this is simplest terms.
