11/17, 5/9, 7/11, 8/15
5/9, 8/15, 11/17, 7/11
11/17, 7/11, 5/9, 8/15

Answer: Option D

3. Evaluate
\begin{aligned}
3.\overline{14}
\end{aligned}

\begin{aligned} 3\frac{14}{99} \end{aligned}
\begin{aligned} \frac{14}{99} \end{aligned}
\begin{aligned} 3\frac{14}{90} \end{aligned}
\begin{aligned} 3\frac{1400}{99} \end{aligned}

Answer: Option A

Explanation:

when there is bar above a number, we can simplify it by dividing with 9's (equal to the number below bar, in this question 2 digits are below bar)

4. What is difference between biggest and smallest fraction among 2/3, 3/4, 4/5 and 5/6

Answer: Option C

Explanation:

2/3 = .66, 3/4 = .75, 4/5 = .8 and 5/6 = .833

So biggest is 5/6 and smallest is 2/3

Their difference is 5/6 - 2/3 = 1/6

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}
