Benny o bone shaka e bolelele jwa yone bo fetang dikgato di le 10 mme e na le ditlhapi tse pedi tse di bidiwang "remoras" tse di kgomaretseng mo go yone, mme nngwe le nngwe e bolelele jwa di-intšhi di le 6. Ke peresente efe ya bolelele jwa shaka e e leng bogolo jwa ditlhapi tse pedi tsa "remoras"  fa di kopane?

There are 30 students in Marissa’s class. Each student started the year with 10 pencils. After two months, 1/5 of the total pencils in class were used. At the end of the year, only 1/3 of the remaining pencils were left. How many pencils were left?
Sa ntlha, bona bolelele jo bo kopantsweng jwa ditlhapi tsa "remoras" ka di-intšhi: 6 inches/tlhapi * ditlhapi di le 2 = <<6*2=12>> di-intšhi di le 12
Morago ga foo, arola palo eo ka 12 go e fetolela mo dikgatong: di-intšhi di le 12 / 12 di-intšhi/leoto = <<1=1>> leoto le le 1
Morago ga foo, arola bolelele jo bo kopantsweng jwa ditlhapi tsa "remoras" ka dikgato ka bolelele jwa shaka mme o bo o atisa ka 100% go tlhagisa karabo jaaka peresente: leoto le le 1 / dikgato di le 10 * 100% = 10%
#### 10% 

There were 30 x 10 = <<30*10=300>>300 pencils in the class at the start of the year.
After two months, 300 x 1/5 = <<300*1/5=60>>60 pencils were used.
Thus, 300 - 60 = <<300-60=240>>240 pencils were left unused after two months.
Therefore, 240 x 1/3 = <<240*1/3=80>>80 pencils were left at the end of the year.
#### 80
