Mark o reka lothare e le nngwe e nang le kgonagalo ya 20% ya go fenya le lothare ya bobedi e nang le kgonagalo ya go fenya e fetang ya ntlha gararo. Kgonagalo ke efe, e tlhalosiwa ka diperesente, ya gore dithare tsoopedi di a fenya?

Patricia has 30 roses. She gave 24 roses to her mother. She bought 15 more roses.  How many roses did she have now?
Sa ntlha, atisa 20% ka boraro go bona kgonagalo ya lothare ya bobedi ya go fenya: .2 * 3 = <<.2*3=.6>>.6
Morago ga foo, atisa dikgonagalo tsa dithare tsoopedi tsa go fenya go bona kgonagalo ya gore tsoopedi di a fenya, mme o atise seo ka 100 go se fetola go nna diperesente: .6 * .2 * 100% = 12%
