### Question 1

What is x in ${722/0.0722} = {7.22/x}$?

### Question 2

What is ${(-27) × 9.6 - 73 × (-3.6)}/9.6$?

**A**

${3/8}$.

**B**

${1/8}$.

**C**

${5/8}$.

**D**

${7/8}$.

**Soln.**

**Ans: a**

Observe that all fractional numbers are having one digit to the right of the dot. So we can cancel all the dots and get a plain expression: ${(-27) × 96 - 73 × (-36)}/96$. We can now simpilfy the minus signs to get ${(73 × 36) - (27 × 96)}/96$ which equals ${3/8}$

### Question 3

Which is the smallest?

**A**

$0.3^3$.

**B**

$1/0.3$.

**C**

$0.3$.

**D**

$0.3^2$.

**Soln.**

**Ans: a**

We know that if a number is less than 1, then it becomes smaller and smaller as it is raised to higher and higher positive powers. Now, $1/0.3$ is same as $0.3^{-1}$. The three powers of 0.3 given to us are -1, 1, 2 and 3. Out of these 3 is the most positive, so, $0.3^3$ is the smallest.

### Question 4

What is $93{97/100000}$?

### Question 5
