[tex]( 6\frac{1}{8} + 2 \frac{3}{4} ) - (2 \frac{3}{4} - 1 \frac{1}{2} ) \\ = ( \frac{49}{8} + \frac{11}{4} ) - ( \frac{11}{4} - \frac{3}{2} ) \\ = ( \frac{49 + 2 \times 11}{8} ) - ( \frac{11 - 2 \times 3}{4} ) \\ = (\frac{49 + 22}{8} ) - ( \frac{11 - 6}{4} ) \\ = \frac{71}{8} - \frac{5}{4} \\ = \frac{71 - 2 \times 5}{8} \\ = \frac{71 - 10}{8} \\ = \frac{61}{8} \\ = \frac{61}{8} \times 100 \%\\ = \frac{6.100}{8} \% \\ = 762.5\%[/tex]

Maaf Kalau Salah

Jawabannya:
(6 1/8+2 2/4)-(2 3/4-1 1/2)
=(49/8+11/4)-(11/4-3/2)
=(49+2×11 /8)-(11-6 /4)
= 71/8-5/4
= 71-2×5 /8
= 71-10 /8
= 61/8
= 61/8. 100%
= 762,5%
