URGENTEE!!

Answer 1

Olá!

a) $0,5555...= \frac{5}{9}$

b) $2,919191...=2+ \frac{91}{99} = \frac{198+91}{99} = \frac{289}{99}$

c) $-5,175175...= -5+ \frac{175}{999} = \frac{-4995+175}{999}= \frac{-5170}{999}$

d) $8,3121212...=8+0,312121...=8+(312-3)/990=8+309/990 \\ (8.990+309)/990= \frac{8299}{990}$

e) $12,264333...= \frac{122643-12264}{9000} = \frac{110379}{9000} = \frac{36793}{3000}$

Espero que te ajude.

Bons estudos!
