Emma o kgona go dira le go tlhaeletsa di-vlog di le 72 ka kgwedi. Mme o kgonne go dira di-vlog di le 18 fela mo bekeng ya ntlha, di le 21 mo bekeng ya bobedi, le di le 15 mo bekeng ya boraro.  O tshwanetse go dira di-vlog di le kae gore a fetse di le 72 tsa kgwedi? 

Chenny is 10 years old. Alyana is 4 years younger than Chenny. How old is Anne if she is 2 years older than Alyana?
Emma o kgonne go dira 18 + 21 + 15 = <<18+21+15=54>>54 di-vlog mo dibekeng di le 3.
Ka jalo, Emma o tshwanetse go dira 72 - 54 = <<72-54=18>>18 di-vlog go tlatsa di le 72.
#### 18 

Alyana is 10 - 4 = <<10-4=6>>6 years old.
So, Anne is 6 + 2 = <<6+2=8>>8 years old.
