A human usually has 20 baby teeth which are replaced by 32 adult teeth roll lost eight of his baby teeth Raul said he lost 4/10 of his baby teeth Anna said roll lost 2/5 of his baby teeth which of these conjectures are true

Both conjectures are true

Step-by-step explanation:

Given data:

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

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
