Expanded form of 78.059 is

0%
$78+\dfrac {5}{10}+\dfrac {9}{100}$
0%
$70+8+0+\dfrac {5}{100}+\dfrac {9}{1000}$
0%
$70+8+\dfrac {5}{10}+\dfrac {9}{100}$
0%
none of these

Explanation

The number system has places. We all know the ones tens hundredths places.

After decimal the first decimal digit from the decimal point is the tenth, the second decimal digit from the decimal point is the hundredth and the third decimal digit from the decimal point is the thousandths digit.

Read the whole set of three decimal digits as a number, and say, "tenths", "hundredths" and “thousandths.” 78.059 has 0 tenths, 5 hundredths, and 9 thousandths.

While 78.059 is the sum of

$70+8+\dfrac{0}{10} +\dfrac{5}{100} + \dfrac{9}{1000}$ .

So option B is the correct answer.

Fraction for 0.04 is:

0%
$\dfrac {4}{10}$
0%
$\dfrac {4}{100}$
0%
$\dfrac {04}{10}$
0%
$\dfrac {4}{1000}$

Explanation

Given:

$0.04$

$=\dfrac{0.04}{1}$

Here, we have two numbers after the decimal point. So, we multiply both the numerator and the denominator by

$100.$

$=\dfrac{0.04\times 100}{1\times 100}$

$=\dfrac{4}{100}$

$\therefore$ Fraction for

$0.04$ is

$\dfrac{4}{100}$

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

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

$\text{It can be seen that Q is after 8 divisions after 1}$

$\Rightarrow \text{Coordinate of Q}=1+8\times\dfrac1{10}=1.8$

$\textbf{Hence , the coordinate of the point Q is }\mathbf{1.8}$

$\textbf{Option B is correct.}$

Express the following in kilograms:

$44kg$

$80gm$ =

$44.08kg$

0%
True
0%

$80$ grams=

$\dfrac{80}{1000}$ kilograms

$80$ grams =

$0.08$ kilograms.

$44$ kg

$80$ grams =

$44+0.080$ kilograms

$44$ kg

$80$ grams=

$44.08$ kilograms.

Which decimal number does the arrow represent?

0%
$6.380$
0%
$6.378$
0%
$6.375$
0%
$6.374$

Explanation

Let the point

$6.37$ is marked as

$A$ and

$6.38$ is marked as

$B$

Length

$AB=6.38-6.37=.01$

Number of units between

$A$ and

$B$

$=10$

Length of each unit

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

Given point is

$8$ units forward from

$6.37$

So, the location of given point

$=6.37+.001\times8=6.378$ .

Hence, option B is correct.

Co-ordinate of

$P$ is :

0%
$2.1$
0%
$2.2$
0%
$2.3$
0%
$2.4$

Explanation

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

$\text{It can be seen that between two whole numbers there are 5 divisions}$

$\Rightarrow \text{1 division}=\dfrac15$

$\text{It can be seen that P is after 1 division after 2}$

$\Rightarrow \text{Coordinate of P}=2+1\times\dfrac15=2.2$

$\textbf{Hence , the coordinate of the point P is }\mathbf{2.2}$

$\textbf{Option B is correct.}$
