Question : The difference of $5.\overline{76}$ and $2.\overline{3}$ is:

Option 1: $2.\overline{54}$

Option 2: $3.\overline{73}$

Option 3: $3.\overline{46}$

Option 4: $3.\overline{43}$

Team Careers360 22nd Jan, 2024

Correct Answer: $3.\overline{43}$


Solution : $5.\overline{76} = 5 + \frac{76}{99}$
$2.\overline{3} = 2 + \frac{3}{9}$
Now,
$5 + \frac{76}{99} - 2 - \frac{3}{9}$
= $3 + (\frac{76}{99} - \frac{3}{9})$
= $3 + (\frac{43}{99})$
= $3\frac{43}{99}$
= $3.\overline{43}$
Hence, the correct answer is $3.\overline{43}$.
