HEY MATE HERES YOUR ANSWER

HOPE THIS WILL HELP YOU

IF THERE IS ANY MISTAKE JUST LET ME KNOW

HCF of 9/10 ,12/25 ,18 ,35 ,21/40

=HCF of nominator /LCM of denominator

HCF (9,12,18,35,21)

9=3 x 3

12= 2 x 2 x 3

18=2 x 3 x 3

35=7 x 5

21=7 x 3

common factor=1

hence HCF (9,12,18,35,21)=1

now

LCM (10,25,1,1,40)=200

hence of given number is

=1/200
