Calcule as expressões

a)2,141414...+0,666...

b)0,4555...+02333...

c) 2,12424...+1,3151515...
​

Answer 1

a)

$\frac{214 - 2}{99} + \frac{06 - 0}{9} = \frac{212}{99} + \frac{6}{9} = \frac{212 + 66}{99} = \frac{278}{99}$

b)

$\frac{045 - 4}{90} + \frac{023 - 2}{90} = \frac{41}{90} + \frac{21}{90} = \frac{62}{90}$

c)

$\frac{2124 - 12}{990} + \frac{1315 - 31}{990} = \frac{2112}{990} + \frac{1284}{990} = \frac{3396}{990}$
