Answer 1

Answer:

Step-by-step explanation:

let the ratios be x. then 5x / 7x for the first case then 5x/7x. take lcm and becomes 20x/28x + 4 = 21x/28x = x = 4. so their ages will be 5 × 4/7 × 4 = 20/28 .... which will be 12/16. four years ago their age would be 8/12 . hence their presrnt age 8 and 12
