Question 1
1 / -0

Solve:
$$\displaystyle 0.126\times 100 $$ is

A
$$12.6$$

B
$$0.126$$

C
$$1.26$$

D
$$126$$

Solution

$$0.126\times100$$
$$ = (126\times100)/1000$$
$$=12.6$$
Hence Option A
Question 2
1 / -0

Which of the following is not a proper fraction?

A
$$\cfrac {2}{3}$$

B
$$\cfrac {3}{4}$$

C
$$\cfrac {5}{7}$$

D
$$\cfrac {6}{5}$$

Solution

Fractions that are greater than $$0$$ but less than $$1$$ are called proper fractions.

In proper fractions, the numerator is less than the denominator.

When a fraction has a numerator that is greater than or equal to the denominator, then the fraction is an improper fraction.

An improper fraction is always $$1$$ or greater than $$1$$.

Now looking at options

$$\dfrac{2}{3}=.666 < 1$$

$$\dfrac{3}{4}= .75 < 1$$

$$\dfrac{5}{7}= .71 <1$$

$$\dfrac{6}{5}=1.2 > 1$$

So $$\dfrac{6}{5}$$ is Not a Proper fraction.

So option $$D$$ is correct.
Question 3
1 / -0

Which of the following is not an improper fraction?

A
$$ \displaystyle \frac{4}{3} $$

B
$$ \displaystyle \frac{3}{2} $$

C
$$ \displaystyle \frac{5}{3} $$

D
$$ \displaystyle \frac{7}{11} $$

Solution

Proper fraction is a fraction that is less than one, with the numerator less than the denominator.
Option $$D$$ is correct.
Question 4
1 / -0

Product of $$\displaystyle \frac {10} {11} \times \frac {15} {3}\times \frac {0} {5}$$ is

A
$$\displaystyle \frac {10} {33} $$

B
0

C
$$\displaystyle \frac {150} {495} $$

D
None of these

Solution

zero multiplied by any number is zero..
So $$\dfrac{10}{11}\times \dfrac{15}{3}\times\dfrac{0}{5}=0 $$
Question 5
1 / -0

Example for an improper fraction is -

A
$$\displaystyle \frac { 35 }{ 36 } $$

B
$$\displaystyle \frac { 11 }{ 4 } $$

C
$$\displaystyle \frac { 12 }{ 14 } $$

D
$$\displaystyle \frac { 17 }{ 20 } $$

Solution

In a fraction, if the denominator is less than the numerator, then it is called as an improper fraction.

Among these, in $$\dfrac {11}{4}$$, the denominator is greater than the numerator.

Hence it is an improper fraction.
Question 6
1 / -0

$$\displaystyle 3 \dfrac { 6 }{ 10 } = \dfrac { ? }{ 10 } $$
Find $$?$$

A
$$63$$

B
$$26$$

C
$$36$$

D
$$62$$

Solution

since we are given a mixed fraction so the resulting fraction will be:
$$=\dfrac { (3\times10)+6 }{ 10 } $$
$$=\dfrac{36}{10}$$
Question 7
1 / -0

The number equal to 22 thousandths is

A
0.22

B
0.022

C
2.022

D
2.202

Solution

$$\frac{22}{1000} = 0.022$$
Question 8
1 / -0

Solve:
$$\displaystyle 122.5 \div 1000 = $$

A
$$.01225$$

B
$$.1225$$

C
$$1.225$$

D
$$12.25$$

Solution

$$122.5/1000$$
$$=1225/10000$$
$$=0.1225$$
Hence Option B
Question 9
1 / -0

Solve:
$$\displaystyle 14.79\times 1000 $$ is

A
$$14709$$

B
$$14790$$

C
$$1479$$

D
$$147.9$$

Solution

$$14.79\times 1000 = 14790$$
Hence Option B
Question 10
1 / -0

Sum of 0.4, 15.46 and 0.002 is -

A
158.62

B
1.5862

C
15.862

D
None of these

Solution

The given numbers are $$0.4,15.46$$ and $$0.002$$
$$\Rightarrow$$ $$15.46+0.4+0.002=15.46+(0.4+0.002)$$
$$=15.46+0.402$$
$$=15.862$$
$$\therefore$$ Sum of $$0.4,15.46$$ and $$0.002$$ is $$15.862$$
