Question

arrange in the descending order is 1/5,3/7,7,10

Answer 1

$\textbf{Solution :}$

“Here, our first task is to make their dinominators equal-after that we need to arrange them.”

The numbers are —

$\frac{1}{5} \: \frac{3}{7} \: \frac{7}{10}$

“to make their dinominators equal, we need to find L.C.M. of the dinominators”

L.C.M. of 5, 7 & 10 = 70

$\frac{1}{5} = \frac{1 \times 14}{5 \times 14} = \frac{14}{70}$

$\frac{3}{7} = \frac{3 \times 10}{7 \times 10} = \frac{30}{70}$

$\frac{7}{10} = \frac{7 \times 7}{10 \times 7} = \frac{49}{70}$

“$\textbf{Descending Order }$ means from the bigger to the smaller ones.”

In descending order—

$\frac{49}{70} > \frac{30}{70} > \frac{14}{70}$

$\frac{7}{10} > \frac{3}{7} > \frac{1}{5}$

Answer 2

Step-by-step explanation:

“Here, our first task is to make their dinominators equal-after that we need to arrange them.”

The numbers are —

\frac{1}{5} \: \frac{3}{7} \: \frac{7}{10}

5

1

7

3

10

7

“to make their dinominators equal, we need to find L.C.M. of the dinominators”

L.C.M. of 5, 7 & 10 = 70

\frac{1}{5} = \frac{1 \times 14}{5 \times 14} = \frac{14}{70}

5

1

=

5×14

1×14

=

70

14

\frac{3}{7} = \frac{3 \times 10}{7 \times 10} = \frac{30}{70}

7

3

=

7×10

3×10

=

70

30

\frac{7}{10} = \frac{7 \times 7}{10 \times 7} = \frac{49}{70}

10

7

=

10×7

7×7

=

70

49

“\textbf{Descending Order }Descending Order means from the bigger to the smaller ones.”

In descending order—

\frac{49}{70} > \frac{30}{70} > \frac{14}{70}

70

49

>

70

30

>

70

14

\frac{7}{10} > \frac{3}{7} > \frac{1}{5}

10

7

>

7

3

>

5
