Ratio of ages
Esi:Kwasi = 12:8
Note: 4 divides 12, 3 times and 8, 2 times.
Esi:Kwasi = 3:2
The sum of ratios represent the total mangoes shared.
Sum of ratios =3+2
Sum of ratios =5
Esi's ratio = 3
Use proportionality to find Esi's share.
If 5=60
3=‌

3×60

5

Note:
1. 5 divides itself 1 and 60, 12 times
2. 3×12=36
Esi got 36 mangoes
