A human usually has 20 baby teeth which are replaced by 32 adult teeth . Raül lost 8 of his baby teeth . Raül said he lost 4/10 of his baby teeth Ana said Raul lost 2/5 . Which of this conjectures are true? Construct an argument to justify your answer.

Respuesta :

They are both right because Raul simplifyed 8/20 to 4/10 but Ana went further to simplify 4/10 to 2/5
They are both correct because Ana simplified what Raul said. You know this because 2/5×2/2=4/10
