Nik o na le dikerayone di le 200. O batla go di kgaoganya ka ditlhopha tsa di le 8 mme a di tsenye mo mabokosong. Lebokose lengwe le lengwe le na le boima jwa di-ounces di le 8. Kerayone nngwe le nngwe e na le boima jwa ounce e le 1. Fa a tsenya dikerayone tsotlhe tsa gagwe mo mabokosong, boima jotlhe jwa dikerayone le mabokoso ke bokae ka di-pounds, fa go na le di-ounces di le 16 mo poundong?

Liam is 16 years old now. Two years ago, Liam’s age was twice the age of Vince. How old is Vince now?
Sa ntlha bona gore Nik o tlhoka mabokoso a makae. Dikerayone di le 200 / dikerayone di le 8 ka lebokose = <<200/8=25>>mabokoso a le 25.
Mabokoso a le 25 * di-ounces di le 8 ka lebokose = <<25*8=200>>di-ounces di le 200.
Kerayone nngwe le nngwe e na le boima jwa ounce e le 1, ka jalo 200 + 200 = <<200+200=400>>di-ounces di le 400.
Di-ounces di le 400 / di-ounces di le 16 ka pound = <<400/16=25>>di-pounds di le 25.

Liam's age two years ago was 16 - 2 = <<16-2=14>>14 years old.
Vince's age two years ago was 14/2 = <<14/2=7>>7 years old because Liam's age is twice his.
So Vince age now is 7 + 2 = <<7+2=9>>9 years old.
