The ration of Jonathan's age to David's is 6:5 in seven years it will be 7:6. Whar are their ages now?
This is my homework, and although I tried many times over was not able to solve it. Can anybody explain? Thanks!!!!
Hello, AlexOrme!
Another approach . . .
We are told that: .$\displaystyle \frac{\text{Jonathan}}{\text{David}} \:=\;\frac{6a}{5a}$ . for some integer $\displaystyle a.$The ratio of Jonathan's age to David's is 6:5
Iin seven years it will be 7:6.
Whar are their ages now?
In seven years, they are both seven years older
. . and the ratio is 7-to-6: . $\displaystyle \frac{6a+7}{5a+7} \:=\:\frac{7}{6}$
Solve for $\displaystyle a$ . . . and then their ages.
