Answer:
LCM of 5 ,10 , 20 , 40 is 40
if we will arrange it in descending order it will be
7/10,13/20,3/5,11/40
Step-by-step explanation:
as as we talked about LCM of 5 10 20 40 that is 40
therefore
3×8/5×8,7×4/10×4,13×2/20×2, we will not change 11 /40 because it have already 40 as a denominator.
when the fractions are multiplied they are written as
3/5 = 24/40
7/10 = 28/40
13/20 = 26/40
11/40 = 11/40
if we will arrange it in descending order
28/40,26/40,24/40,11/40
therefore the arrangement of the fraction into descending order is is
7/10,13/20,3/5,11/40
I hope it will help you
