Go na le baithuti ba le 40 mo phaposing. Sephatlo sa baithuti ba rata mmala o botala jwa legodimo. Kwatara ya ba ba setseng ba rata mmala o motala mme ba bangwe botlhe ba rata mmala o serolwana. Ke baithuti ba le kae ba ratang mmala o serolwana? 

Mary has 30 sheep. She gets 1 kg of milk from half of them and 2 kg of milk from the other half every day. How much milk does she collect every day?
Go na le baithuti ba le 40/2 = <<40/2=20>>20 ba ba ratang mmala o botala jwa legodimo.
Jalo he, go setse baithuti ba le 40 - 20 = <<40-20=20>>20 ba ba ratang mmala o motala kgotsa o serolwana. 
Go tswa foo, baithuti ba le 20/4 = <<20/4=5>>5 ba rata mmala o motala.
Ka jalo, baithuti ba le  20 - 5 = <<20-5=15>>15 ba rata mmala o serolwana.

Half of the sheep is 30 / 2 = <<30/2=15>>15.
Mary gets (15 * 1) + (15 * 2) = <<15*1+15*2=45>>45 kg of milk every day.
