Question

Determine a fração geratriz das dízimas: 2,4777... 3,151515... 4,03222... 5,04333...

Answer 1

2,4777... = $\frac{247-24}{90}$ = $\frac{223}{90}$

3,151515... = 3 + 0,151515... = 3 + $\frac{15}{99}$ = $\frac{99.3+15}{99}$ = $\frac{297+15}{99}$ = $\frac{312}{99}$

4,03222... = $\frac{4032-403}{900}$ = $\frac{3629}{900}$

5,04333... = $\frac{5043-504}{900}$ = $\frac{4539}{900}$
