Penjelasan dengan langkah-langkah:
[tex]9 - 1 \frac{1}{2} = \frac{9}{1} - \frac{3}{2} = \frac{18}{2} - \frac{3}{2} = \frac{18 - 3}{2} = \frac{15}{2} [/tex]
[tex] \frac{15}{2} - 3 \frac{1}{4} = \frac{30}{4} - \frac{13}{4} = \frac{30 - 13}{4} = \frac{17}{4} [/tex]
[tex] \frac{17}{4} - 2 \frac{1}{2} = \frac{17}{4} - \frac{5}{2} = \frac{17}{4} - \frac{10}{4} = \frac{17 - 10}{4} = \frac{7}{4} = 1 \frac{3}{4} [/tex]
= 1¾ liter
