How much sugar did she use in all?

$\underline{\sf Answer:}$ She used 6 3/8 kg of sugar in all.

$\sf solution : \boxed{ \sf2 \frac{3}{4} + 3 \frac{5}{8} = 2 \frac{6}{8} + 3 \frac{5}{8} = 5 \frac{11}{8} \: or \: 6 \frac{3}{8} }$

How much sugar was left in the container?

$\underline{\sf Answer:}$ The sugar was left in the container was 2 1/8 kg of sugar.

$\sf solution : \boxed{ \sf8 \frac{1}{2} - 6 \frac{3}{8} = 8 \frac{4}{8} - 6 \frac{3}{8} = 2 \frac{1}{8} }$

$\underline{\sf Answer:}$ The liters were left over is 9 1/4 liters.

$\sf solution \: \#1 : \boxed{ \sf 4 \times 2 \frac{1}{2} = \frac{4}{1} \times \frac{5}{2} = \frac{20}{2} = 10 }\\ \\ \\ \sf solution \: \#2 : \: \: 10 - 6 \frac{3}{4} \\ \\ \sf\frac{10}{1} \times \frac{4}{4} = \frac{40}{4} \\ \sf6 \frac{3}{4} = 6 \frac{3}{4} \\ \\ \sf \frac{40}{4} - 6 \frac{3}{4} = 6 \frac{37}{4} \: or \: 9 \frac{1}{4}$
