Bagasi ba molelo ba lefelo la lona ba tshwere letsholo la go kokoanya madi ka go dirisa 'butu'. Maikaelelo a bone ke go kokoanya R6300. Morago ga diura di le 3, ba kgonne go kokoanya R2100. Ba tshwanetse go kokoanya madi ka diura di le kae gore ba fitlhelele maikaelelo a bone, fa re tsaya gore ba kokoanya madi a a lekanang ka ura?

Gerald and Julia divided $100 in the ratio 3:2. If Gerald spent $10 on a book, how much money did he have left?
Bagasi ba molelo ba kokoanya R2100 / 3 = R<<2100/3=700>>700 ka ura.
Ba tshwanetse go kokoanya madi ka diura di le 6300 / 700 = <<6300/700=9>>9.

The $100 was divided into 3 + 2 = <<3+2=5>>5 parts.
So each part is $100/5 = $<<100/5=20>>20.
So Gerald received $20 x 3 = $<<20*3=60>>60.
Gerald bought a book at $<<10=10>>10.
Therefore, Gerald was left with $60 - $10 = $<<60-10=50>>50.
