Dingwaga tsa ga rraagwe Dora di feta tsa ga Dora gabedi ka di le robedi. Fa mmaagwe Dora a le mmotlana go rraagwe Dora ka dingwaga di le nne, mme Dora a le dingwaga di le 15, bala palogotlhe ya dingwaga tsa ga Dora, rraagwe, le mmaagwe. 

Parker chews 4 pieces of gum a day.  A pack of gum has 15 pieces of chewing gum per pack.  How many packs of gum will he need to last him 30 days?
Fa dingwaga tsa ga Dora di le 15, rraagwe, yo o mogolo go feta Dora gabedi ka di le robedi, o feta 15*2 = <<15*2=30>>30 ka di le robedi.
Seno se raya gore rraagwe Dora o na le dingwaga di le 30+8 = <<30+8=38>>38.
Fa ba kopane, Dora le rraagwe ba na le dingwaga di le 38+15 =<<38+15=53>>53.
Mmaagwe Dora o mmotlana go rraagwe Dora ka dingwaga di le nne, se se rayang gore mmaagwe Dora o na le dingwaga di le 38-4 = 34.
Fa ba kopane botlhe, ba lelapa la ga Dora ba na le dingwaga di le 53+34 = <<53+34=87>>87.

He chews 4 pieces of gum a day so over 30 days he will chew 4*30 = <<4*30=120>>120 pieces of gum
Each pack of gum holds 15 pieces and he needs 120 pieces for the month so he will need 120/15 = <<120/15=8>>8 packs of gum
