    Both conjectures are true

    Step-by-step explanation:

    Given dа ta:

    20 baby teeth

    32 adult teeth

    Roll lost 8 baby teeth

    Teeth lost = lost teeth / total number of teeth

    teeth lost = 8/20

    Reducing the fraction to its lowest terms

    8/20 = 4/10 = 2/5

    Conclusion

    Both conjectures are true as they are representing the same thing
