Changing ratio method.The ratio of Sally's age to Peter's age is 9:5.
The ratio of Simon's age to Peter's age is 3:2.
Find the ratio of Sally's age to Simon's to Peter's
Since Peter appeared to compare with 2 different people, however, he is still the same. So we have to find a common multiple to convert his ratio to be the same. Normally, take the 2 numbers of Peter's ratio to cross times each other.
Sally:Peter
(x2) 9:5 (x2)
18:10
Simon:Peter
(x5) 3:2 (x5)
15:10
Sally:Simon:Peter
18:15:10
Hope it's easy to understand -
