Out of these which are proper fractional numbers?

0%
$\displaystyle\frac{3}{2}$
0%
$\displaystyle\frac{2}{5}$
0%
$\displaystyle\frac1{7}$
0%
$\displaystyle\frac{8}{3}$

Explanation

Proper fractions are the one whose numerator is less than the denominator

\frac{3}{2}

$\dfrac{3}{2}$ and

\frac{8}{3}

$\dfrac{8}{3}$ , the numerator is greater than the denominator

So, they are not proper fractions

Whereas in

\frac{2}{5}

$\dfrac{2}{5}$ and

\frac{1}{7}

$\dfrac{1}{7}$ , the numerator is less than the denominator

Thus, they are proper fractions.

Hence,

\frac{2}{5}

$\dfrac{2}{5}$ and

\frac{1}{7}

$\dfrac{1}{7}$ are proper fractional numbers.

Which of these are improper fractional numbers?

0%
$\displaystyle\frac{2}{7}$
0%
$\displaystyle\frac{7}{11}$
0%
$\displaystyle\frac{13}{2}$
0%
$\displaystyle\frac{7}8$

Explanation

Improper fractions are the one who numerator is more than the denominator

\frac{13}{2}

$\dfrac{13}{2}$ and

\frac{7}{3}

$\dfrac{7}{3}$ , the numerator is greater than the denominator

So, they are not proper fractions

Whereas in

\frac{2}{7}

$\dfrac{2}{7}$ and

\frac{7}{11}

$\dfrac{7}{11}$ , the numerator is less than the denominator

Thus, they are proper fractions.

Hence,

\frac{13}{2}

$\dfrac{13}{2}$ and

\frac{7}{3}

$\dfrac{7}{3}$ are improper fractional numbers.

$30+\cfrac { 3 }{ 10 } +\cfrac { 3 }{ 1000 }$

0%
True
0%
False

Explanation

30.303 = 30 + 0.3 + 0.003

$30.303 = 30 + 0.3 + 0.003$

= 30 +

$= 30 +$

\frac{3}{10} + \frac{3}{1000}

$\dfrac{3}{10} + \dfrac{3}{1000}$

So, given statement is true

State true or false:

303.03

$303.03$ is equal to

300 + 3 + \frac{3}{10}

$300+3+\cfrac { 3 }{ 10 }$

0%
True
0%
False

Explanation

The correct expanded form of the decimal number

303.03

$303.03$ will be,

303.03 = 300 + 3 + 0.03

$303.03 = 300 + 3 + 0.03$

= 300 + 3 +

$= 300 + 3 +$

\frac{3}{100}

$\dfrac{3}{100}$

Hence, the given statement is false.

State true/false:

$55.5$ is equal to

50 + 5 + \frac{5}{10}

$50+5+\cfrac { 5 }{ 10 }$

0%
True
0%
False

Explanation

We can write

55.5

$55.5$ as

50 + 5 + 0.5

$50 + 5 +0.5$

= 50 + 5 +

$= 50 + 5 +$

\frac{5}{10}

$\dfrac{5}{10}$

Solve the following:

0.2 \times 210.8

$0.2\times 210.8$

Ans :

42.16

$42.16$

0%
True
0%
False

Explanation

Remove the decimal points and perform multiplication without decimal point.

\Rightarrow 2 \times 2108 = 4216

$\Rightarrow 2\times 2108=4216$

Now it is known that in the number

0.2

$0.2$ and

210.8

$210.8$ decimal point is present before last digit that is one place from right. Thus, in the number obtained

4216

$4216$ decimal point will be present after two places from right.

Thus,

0.2 \times 210.8 = 42.16

$0.2\times 210.8=42.16$

Solve the following:

11.2 \times 0.10

$11.2\times 0.10$

Ans :

1.12

$1.12$

0%
True
0%
False

Explanation

$11.2 \times 0.10$

Step I: $112 \times 10=1120$

Step II: Total number after decimal point $= 1 + 2 = 3$

So, we put a decimal point after three places from the right

$11.2 \times 0.10 = 1.120$

$= 1.12$

State true or false:

0.5 \times 0.05

$0.5\times 0.05$

= 0.025

$=0.025$

0%
True
0%
False

Explanation

Given,

0.5 \times 0.05

$0.5 \times 0.05$

0.5

$0.5$ has

1

$1$ decimal place whereas

0.05

$0.05$ has

2

$2$ decimal places, so the product must have

3

$3$ decimal places.

We know

5 \times 5 = 25

$5 \times 5 = 25$

So,

0.5 \times 0.05 = 0.025

$0.5 \times 0.05 = 0.025$

Hence , given statement is true

Solve the following:

4.3 \times 3.4

$4.3\times 3.4$

Ans:

14.62

$14.62$

0%
True
0%
False

Explanation

Given,

4.3 \times 3.4

$4.3 \times 3.4$

Step I:

43 \times 34 = 1462

$43 \times 34 = 1462$

Step II: Total number after decimal

= 2

$= 2$

So,

4.3 \times 3.4 = 14.62

$4.3 \times 3.4 = 14.62$

Hence , given statement is true

Solve the following:

$101.01 \times 0.01$

Step I:

$10101 \times 001 = 10101$

Step II: Total number after decimal

$= 4$

So,

$101.01 \times 0.01 = 1.0101$

Hence , given statement is true

State True/False.

$10.05\times 1.05=10.5525$

0%
True
0%
False

Explanation

Given,

$10.05 \times 1.05$

Step I:

$1005 \times 105 = 105525$
