7/10 ,3/7 ,1/5

Answer 2

“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}

5×14

1×14 =  70

14

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

3/7

=

7×10 = 70

3×10 = 30

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

7/10

= 10×7=70

7×7=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}

49/70 >30/70>14/70

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

7/10 >3/7>1/5
