0%
proper
0%
improper
0%
mixed
0%

Which of the following is not a proper fraction ?

0%
$\displaystyle \frac{2}{3}$
0%
$\displaystyle \frac{3}{4}$
0%
$\displaystyle \frac{5}{7}$
0%
$\displaystyle \frac{6}{5}$

Explanation

Proper fraction is a fraction that is less than one, with the numerator less than the denominator.

So, option

$D$ is correct.

$\displaystyle 0.04\times 0.08\times 4$ is equal to

0%
$0.012$
0%
$0.128$
0%
$0.00128$
0%
$0.0128$

Explanation

Here,

$0.04$ has

$2$ places decimal and

$0.08$ also has

$2$ places. So the total decimal places are

$4$ .

So, the product will also have

$4$ decimal places from the right.

$0.04×0.08×4=0.0128$

So option D is the correct answer.

Solve:

$\displaystyle 0.126\times 100$ is

0%
$12.6$
0%
$0.126$
0%
$1.26$
0%
$126$

Explanation

$0.126\times100$

$= (126\times100)/1000$

$=12.6$

Hence Option A

Which of the following is not a proper fraction?

0%
$\cfrac {2}{3}$
0%
$\cfrac {3}{4}$
0%
$\cfrac {5}{7}$
0%
$\cfrac {6}{5}$

Explanation

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

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

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

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

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

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

So option

$D$ is correct.

Example for an improper fraction is -

0%
$\displaystyle \frac { 35 }{ 36 }$
0%
$\displaystyle \frac { 11 }{ 4 }$
0%
$\displaystyle \frac { 12 }{ 14 }$
0%
$\displaystyle \frac { 17 }{ 20 }$

Explanation

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.

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

Find

$?$

0%
$63$
0%
$26$
0%
$36$
0%
$62$

Explanation

since we are given a mixed fraction so the resulting fraction will be:

$=\dfrac { (3\times10)+6 }{ 10 }$

$=\dfrac{36}{10}$

Sum of 0.4, 15.46 and 0.002 is -

0%
158.62
0%
1.5862
0%
15.862
0%
None of these

Explanation

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

$15.862$

Sum of

$1.8, 16.3$ and

$72.985$ is _____
