Solution
Question 2
1 / -0

$$3$$ tenths $$ 5$$ thousandths is written as

A
$$35.00$$

B
$$0.35$$

C
$$3.5$$

D
$$0.305$$

Solution

3 tenths 5 thousandth =$$3\times \dfrac{1}{10}+5\times \dfrac{1}{1000}$$$$=0.3+0.005=0.305 $$
Question 3
1 / -0

Co-ordinate of $$P$$ is.

A
$$-0.6$$

B
$$0.3$$

C
$$0.4$$

D
$$-0.4$$

Solution

$$\textbf{Step 1: Using number line}$$
$$\text{It can be seen that between two whole numbers there are 10 divisions.}$$
$$\Rightarrow \text{1 division}=\dfrac1{10}$$
$$\text{It can be seen that P is after 6 divisions.}$$
$$\Rightarrow \text{Coordinate of P}=6\times\dfrac1{10}=-0.6$$
$$\text{The negative sign is because the point is to the left of 0.}$$
$$\textbf{Hence , the coordinate of the point P is}\mathbf{-0.6.}$$ $$\textbf{Option A is correct.}$$
Question 4
1 / -0

Represent $$4.5$$ and $$-2.3$$ on a number line and find the distance between them.

A
$$6.8$$

B
$$2.2$$

C
$$-6.8$$

D
$$-2.2$$
Question 5
1 / -0

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

A
$$10.360$$

B
$$10250$$

C
$$1.250$$

D
$$10.625$$

Solution

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, $$1\ km$$ $$250\ m$$=$$1.25\ km$$
Question 6
1 / -0

Which decimal number does arrow represent?

A
$$3.05$$

B
$$3.025$$

C
$$3.005$$

D
$$3.004$$

Solution

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.
Question 7
1 / -0

Fill in the banks:
$$1765$$ grams $$= $$ _______ $$kg$$

A
$$1.765$$

B
$$1.65$$

C
$$1.55$$

D
$$1.25$$

Solution

$$1$$ kg $$= 1000$$ gm

So, $$1765$$ grams $$= \dfrac{1765}{1000}$$ kg

$$= 1.765$$ kg
Question 8
1 / -0

Rahul bought $$4kg$$ $$90g$$ of apples, $$2kg$$ $$60g$$ of grapes and $$5kg$$ $$300g$$ of mangoes. The total weight of all the fruits he bought is _______ .

A
$$11.000kg$$

B
$$11.450kg$$

C
$$11.350kg$$

D
$$11.250kg$$

Solution
Question 9
1 / -0

Golu's toothbrush is $$14.5\ cm$$ long and Samaksh's toothbrush is $$12.8\ cm$$ long. How much longer is Golu's toothbrush than Samaksh?

A
$$1.7\ cm$$

B
$$1.6\ cm$$

C
$$2.7\ cm$$

D
$$1.9\ cm$$

Solution

Length of Golu's toothbrush $$= 14.5\ cm$$
Length of Samaksh's toothbrush $$= 12.8\ cm$$
Required difference in lengths $$= (14.5 - 12.8) cm$$
$$= 1.7\ cm$$.
