Question

the sum of two positive integers is 98. the integer are in the ratio of 3: 4.Find the integers.​

Answer 1

You appear to have 2 different problem statements, one in the title and one in the description.  I will assume the one in the title is correct, and I will work that one.

 

n + m = 98

 

n/m = 3/4

 

n = (3/4)m

 

(3/4)m + m = 98

 

(7/4)m = 98

 

m = (4/7)98 = 56

 

n = 98 - m = 98 - 56 = 42

 

Note that

 

n/m = 42/56 = 3/4
