Question

if m+n : m-n = 19:5 find m:n value​

Answer 1

Answer:

24:14 or 12:7

Step-by-step explanation:

m+n/m-n=19/5

now cross multiply them

5m+5n=19m-19n

bring the terms having m on one side and terms having n on one side

-14m=-24n

14m=24n

m/n=24/14

or.....m/n=12/7

m:n=12:7

Answer 2

★${\red{\boxed{\huge{\bold{Given:-}}}}}$

m+n : m-n= 19:5

★${\red{\boxed{\huge{\bold{To\: Find:-}}}}}$

Value of m:n

★${\red{\boxed{\huge{\bold{Solution:-}}}}}$

m+n : m-n = 19 : 5

$= > \frac{m + n}{m - n} = \frac{19}{5} \\ = > \frac{m + n + m - n}{m + n - m + n} = \frac{19 + 5}{19 - 5} \\ = > \frac{2m}{2n} = \frac{24}{14} \\ = > \frac{m}{n} = \frac{12}{7}$

=> m : n = 12 : 7

★${\red{\boxed{\huge{\bold{Answer:-}}}}}$

Value of m : n is 12 : 7.
