Nancy o tlhapa ntlwana ya gagwe ya dikgong tsa bogologolo. O bone dikwena di le 90, di-millipede di le 1/3 ya palo ya dikwena, le di-stink bug tse di lekanang gabedi palo ya di-millipede go fokotswe 12. O badile dikokoni di le kae ka palo yotlhe? 

Jenny is dividing up a pizza with 12 slices. She gives 1/3 to Bill and 1/4 to Mark. If Jenny eats 2 slices, how many slices are left?
Sa ntlha batla palo ya di-millipede: Dikwena di le 90 / 3 dikwena/millipede = <<90/3=30>>30 di-millipede
Morago ga foo atisa palo ya di-millipede ka 2: Dikokoni di le 30 * 2 = <<30*2=60>> Dikokoni di le 60
Morago ga foo fokotsa ka 12 go bona palo ya di-stink bug: Dikokoni di le 60 - dikokoni di le 12 = <<60-12=48>> Dikokoni di le 48
Morago ga foo tlhakanya palo ya mofuta mongwe le mongwe wa kokoanyana go bona palo yotlhe: Dikokoni di le 48 + dikokoni di le 30 + dikokoni di le 90 = <<48+30+90=168>> Dikokoni di le 168
#### 168 

First find how many slices 1/3 of the pizza is by multiplying 1/3 by the total number of slices: 12 slices * 1/3 = <<12*1/3=4>>4 slices
Do the same thing to find how many slices 1/4 of the pizza is: 12 slices * 1/4 = <<12*1/4=3>>3 slices
Then subtract the slices each of the three people ate to find the remaining number of slices: 12 slices - 4 slices - 3 slices - 2 slices = <<12-4-3-2=3>>3 slices
