In which figure does the shaded part represents 0.3?

Explanation

In figure A,

Total Divisions

$= 10$

Shaded Divisions

$= 3$

$\therefore\$ Shaded part

$= \dfrac{3}{10} = 0.3$

In figure B,

Total Divisions

$= 4$

Shaded Divisions

$= 1$

$\therefore\$ Shaded part

$= \dfrac{1}{4} = 0.25$

In figure C,

Total Divisions

$= 4$

Shaded Divisions

$= 1$

$\therefore\$ Shaded part

$= \dfrac{1}{4} = 0.25$

0%
$-0.6$
0%
$0.3$
0%
$0.4$
0%
$-0.4$

Explanation

$\textbf{Step 1: Using number line}$

$\text{It can be seen that between two whole numbers there are 10 divisions.}$

$\Rightarrow \text{1 division}=\dfrac1{10}$

$\text{It can be seen that P is after 6 divisions.}$

$\Rightarrow \text{Coordinate of P}=6\times\dfrac1{10}=-0.6$

$\text{The negative sign is because the point is to the left of 0.}$

$\textbf{Hence , the coordinate of the point P is}\mathbf{-0.6.}$

$\textbf{Option A is correct.}$

State true or false:

$9$ paise is equal to Rs.

$0.09$ .

0%
True
0%

$\frac{9}{100}$ Rs

= 0.09 Rs

State true or false:

$10cm$ in meters is

$0.1$

$m$

0%
True
0%
False

Explanation

As we know,

$1$ m

$= 100$ m

$1$ km

$= 1000$ m

Given,

$10$ cm

So,

$10$ cm

$= \dfrac{10}{100}$ m

$= 0.1$ m

On expressing the following in kilograms:

$247$

$g$ =

$2.47$

$kg$

0%
True
0%
False

Explanation

To convert grams into kilograms we divide the given value by 1,000. A kilogram is one thousand grams.

$247$ grams

$=$

$\dfrac{247}{1000}$ kilograms

$247$ grams

$=$

$0.247$ kilograms

$0.247≠2.47$

So the given statement is false.

Option B is the correct answer

$1\ km\ 250\ m =....................km$
Fill in the blank by chosing correct option from the following options

0%
$10.360$
0%
$10250$
0%
$1.250$
0%
$10.625$

Explanation

We know that

$1\ m$ =

$1000\ km$ .

Now, let us convert

$250\ m$ in kms by dividing it by

$1000$ as follows:

$\dfrac {250}{1000}=0.25$

Therefore,

$250\ m$ =

$0.25\ km$

Thus we have:

$1\ km$

$250\ m$ =

$(1+0.25)\ km$ =

$1.25\ km$

Hence,

$1\ km$

$250\ m$ =

$1.25\ km$

Which decimal number does arrow represent?

0%
$3.05$
0%
$3.025$
0%
$3.005$
0%
$3.004$

Explanation

Let the marking

$3.00$ is at

$A$ and

$3.01$ is at

$B$

$AB=3.01-3.00=.01$

Number of units betwwen

$A$ and

$B$

$=10$

Length of each unit

$=\dfrac{.01}{10}=.001$

Given point is

$5$ units from

$3.00$

So location of given point is

$=3.00+.001\times5=3.005$

Option

$C$ is correct.

State true or false:

$77$ rupees

$7$ paise is equal to Rs.

$77.07$ .

0%
True
0%
False

Explanation

As we know,

1 Rs

$=$ 100 paisa

Given, 77 Rs 7 paisa

So, 77 Rs 7 paisa

$=$ 77 +

$\frac{7}{100}$ Rs

$=$ 77 + 0.07 Rs

$=$ 77.07 Rs

so answer is true

True
0%
False

Explanation

Given 1234.56 can be written as

$1234.56 = 1000 + 200 + 30 + 4 + 0.5 + 0.6$

$= 1000 + 200 + 30 + 4 +$

$\dfrac{5}{10}$ +

$\dfrac{6}{100}$

So, given statement is true
