You can put this solution on YOUR website! mother was 35 when girl was born. Girl now 15, mother 35+15 = 50
the girl is 15/50.
.
Imagine this is a cake. The whole cake is divided into 50 slices. The daughter is the equivalent of 15 slices, or 15 out of 50; you can also write it as 15:50 or as 15/50
.
In the last case, 15/50, you need to simplify by finding common factors for these two numbers:
.
15 is divisible by 1, 3, 5, 15
50 is divisible by 1, 2, 5, 10, 25, 50
so the only common factor is 5:
15/5 = 3
50/5 = 10
the girl is 3/10 her mother's age
