Question

M:N=7:9 and N:L=11:13 ,then M:N:L=?

Answer 1

Step-by-step explanation:

please mark as brainlest

Answer 2

M : N = 7 : 9 ___ ( i )

N : L = 11 : 13 ___ ( ii )

in both the equations N is common so we have fund the LCM of the numbers 9 and 11

so LCM is 99

now multiply equations ( i ) with 11

and equations ( ii ) with 9

HENCE WE GET

M :N = 77 : 99

N : L = 99 : 117

THEREFORE

M =77

N =99 and

L = 117

SO ,

M : N : L = 77 : 99 : 117
