Answer:
Explanation:
Ana's conjecture that Raul lost 2/5 of his baby teeth is true.
To see why, consider that Raul originally had 20 baby teeth. If he lost 8 of these teeth, that means he has 20 - 8 = 12 baby teeth remaining. To determine what fraction of his baby teeth he lost, we can calculate:
8 baby teeth lost / 20 baby teeth total = 2/5
So, Raul lost 2/5 of his baby teeth, which supports Ana's conjecture.
On the other hand, Raul's statement that he lost 4/10 of his baby teeth is not correct, since 4/10 can be simplified to 2/5, which is the same as Ana's conjecture that he lost 2/5 of his baby teeth.
