Basadi ba bararo mo moletlong ba rwele ditlhako tsa di-inches di le 4 mme ba bangwe ba bararo ba rwele ditlhako tsa di-inches di le 2. Go lekana bokae palogare ya bogodimo jwa ditlhako mo moletlong ono? 

How many girls are in the school if 40% of a school population is made up of 240 boys?
Sa ntlha bona palogotlhe ya di-inches tsa ditlhako tsa di-inches di le 4: Basadi ba le 3 * 4 di-inches/mosadi = <<3*4=12>>12 di-inches
Morago o bone palogotlhe ya di-inches tsa ditlhako tsa di-inches di le 2: Basadi ba le 3 * 2 di-inches/mosadi = <<3*2=6>>6 di-inches
Morago o tlhakanye palogotlhe ya di-inches go tswa mo ditlhopheng tse pedi tsa ditlhako go bona palogotlhe: 12 di-inches + 6 di-inches = <<12+6=18>>18 di-inches
Morago o bone palogotlhe ya basadi ba ba leng teng mo moletlong: Basadi ba le 3 + Basadi ba le 3 = <<3+3=6>>6 basadi
Morago o arogane palogotlhe ya di-inches tsa ditlhako ka palo ya basadi go bona palogare ya bogodimo jwa ditlhako mo mosadi mongwe le mongwe: 18 di-inches / Basadi ba le 6 = <<18/6=3>>3 di-inches / mosadi

100% - 40% = 60% of the school's population are girls.
Since 40% is equal to 240 students, then 1% is equal to 240/40 = <<240/40=6>>6 students.
Hence, there are 60 x 6 = <<60*6=360>>360 girls.
