Question

arange in ancending order 4/9 ,2/5 ,3/7 ​

Answer 1

Step-by-step explanation:

First take the LCM of the denominator 9, 5 and 7

that is 315 then =

4/9 = 4×35=140 , 9×35= 315

2/5 = 2×63=126 , 5× 63 = 315

3/7 = 3×45=135 , 7×45 = 315

140/315, 126/315, 135/315

ascending order= 2/5, 3/7, 4/9 so this is your answer

I hope it was helpful for you

Answer 2

(2/5) < (3/7) < (4/9)

explanation

4/9 , 2/5 , 3/7

as the denominator is not same we cannot compare, therefore we have to make the denominator same , by taking LCM

LCM of 9,5,7 = (9×5×7) = 315

4/9 = (4×35)/(9×35) = 140/315

2/5 = (2×63)÷(5×63) = 126/315

3/7 = (3×45)÷(7×45) = 135/315

now we can compare them

therefore,

(126/315) < (135/315) < (140/315)

=> (2/5) < (3/7) < (4/9)
