Answer:
548 and 213
Step-by-step explanation:
Use a linear function:
Let x = 1st number
Let y = 2nd number
x+y=761
x-y=335
2x=1096
x=548
plug x into either equation
548+y=761
y=761-548
y=213
548-y=335
-y=-213
y=213
It would be: 5/45 = 1/9 = 10/90 = 15/135
[You can reduce it, or can multiply both numerator & denominator with a same number at a time and you'll get your answer]
