1. Correct expression of \begin{aligned}
6.\overline{46}
\end{aligned} is

\begin{aligned} \frac{640}{99} \end{aligned}
\begin{aligned} \frac{640}{90} \end{aligned}
\begin{aligned} \frac{64000}{99} \end{aligned}
\begin{aligned} \frac{640}{9} \end{aligned}

Answer: Option A

Explanation:

\begin{aligned}
6.\overline{46} = 6 + 0.\overline{46}
= 6 + \frac{46}{99}
= 6\frac{46}{99} = \frac{640}{99}
\end{aligned}

2. Which is in ascending order

3/2, 9/11, 7/9, 8/9
3/2, 7/9, 9/11, 8/9
9/11, 8/9, 3/2, 7/9
7/9, 3/2, 9/11, 8/9

Answer: Option B

3. Arrange the fractions in ascending order

5/8 < 7/12 < 3/4< 13/16
5/8 < 7/12 < 13/16 < 3/4
5/8 < 3/4< 13/16 < 7/12
7/12 < 5/8 < 3/4< 13/16

Answer: Option D

Explanation:

5/8 = .625, 7/12 = .5833, 3/4 = .75, 13/16 = .8125

So order will be
7/12 < 5/8 < 3/4< 13/16

4. 1/0.04 is equal to

5. Evaluate
\begin{aligned}
\frac{3.6 \times 0.48 \times 2.50}{0.12 \times 0.09 \times 0.5}
\end{aligned}

80
800
8000
80000

Answer: Option B

Explanation:

\begin{aligned}
\frac{3.6 \times 0.48 \times 2.50}{0.12 \times 0.09 \times 0.5}
\end{aligned}

\begin{aligned}
= \frac{36 \times 48 \times 250}{12 \times 9 \times 5} = 800
\end{aligned}
