solution:- 4/7+ 5/9+ 2/5

LCM of 7, 9, 5=> 315.

then,
(188+ 195+ 122)/315
ascending order:- 122/315, 188/315, 195/315

so,
Ascending order=>

2/5 , 4/7 , 5/9.

hope it's help you

Answer 2

Answer:

So, The required ascending order is : 2/5 , 5/9 , 4/7

Step-by-step explanation:

The numbers which are to be arranged in the ascending order are given to be :

$\frac{4}{7},\frac{5}{9},\frac{2}{5}$

Now, the L.C.M. of 7, 9 and 5 is 315

So, making the denominator of all the three numbers 315

$\implies\frac{4\times 45}{7\times 45},\frac{5\times 35}{9\times 35},\frac{2\times 63}{5\times 63}\\\\\implies \frac{180}{315},\frac{175}{315},\frac{126}{315}$

Now, the denominator of all the three numbers are same, so the numbers will be arranged in ascending order in the same way as the increasing order of their numerator

⇒ 126 < 175 < 180

So, The required ascending order is : 2/5 , 5/9 , 4/7
