1. Пусть одно число равно х, тогда второе число равно 7х. Из условия следует:

7х - х = 2

6х = 2

х = 1/3

Таким образом, первое число равно 1/3, а второе число равно 7/3.

2. Пусть одно число равно х, тогда второе число равно 9х. Из условия следует:

х + 9х = 16

10х = 16

х = 1.6

Таким образом, первое число равно 1.6, а второе число равно 14.4.
