Question

if l:m=5/2:5/3 and m:n=5/4:7/2 find l:m:n​

Answer 1

Answer:

hi there

5/2:5/3  can be written simply

LCM of  2 and 3 is 6

soo multiply both numerator and denominator of 5/2 with 3

we get 15/6

in the same way multiply both num and den of 5/3 with 2

we get 10/6

now take the ratio

l:m = (15/6) : (10/6)

     = 15:10

      = 3: 2

in the same way ....

for m:n

lcm of 4 and 2 is 4

soo

l:m= 3:2

m:n = 5: 14

now l:m:n

multiply 3 with 5

soo 15

2*5 = 10

5*2 = 10

14*2 = 28

therefore ratio is 15 : 10: 28  

hope it helps.........

Answer 2

Answer:

Step-by-step explanation:

'n=5/14 m;3. l/m/n= 3/2 m: m: 5/14 m; ⇒ l/m/n=3/2:1:5/14 (or l/m/n=21/1/5)' write as 'n=14/5 m;3. l/m/n= 3/2 m: m: 14/5 m; ⇒ l/m/n=3/2:1:14/5 (or l/m/n=15/10/28)
