Katy o dira kofi a dirisa dikgabana tsa sukiri le dikopi tsa metsi ka lobelo la 7:13. Fa a dirisitse palogotlhe ya dikgabana tsa sukiri le dikopi tsa metsi di le 120, bala palo ya dikgabana tsa sukiri tse a di dirisitseng. 

Katy makes coffee using teaspoons of sugar and cups of water in the ratio of 7:13. If she used a total of 120 teaspoons of sugar and cups of water, calculate the number of teaspoonfuls of sugar she used.
Lobelo lo lo totobetseng metsoako e a e dirisitseng go dira kofi ke 7+13 = <<7+13=20>>20
E re ka palophatlo e e emelang palo ya dikgabana tse a di dirisitseng e le 7/20, o dirisitse 7/20*120 = <<7/20*120=42>>42

The total ratio representing the ingredients she used to make the coffee is 7+13 = <<7+13=20>>20
Since the fraction representing the number of teaspoons she used is 7/20, she used 7/20*120 = <<7/20*120=42>>42
