Jawaban Nomor 1 :
[tex] \frac{1}{2} - \frac{1}{4} + \frac{1}{8} \\ [/tex]
[tex] = \frac{4}{8 } - \frac{2}{8} + \frac{1}{8} \\ [/tex]
[tex] \tt \gray {= \frac{3}{8} } \\ [/tex]
--
[tex] \\ \\ \\ \\ \\ \\ \\ \\ \\ [/tex]
Jawaban Nomor 2 :
[tex] \frac{15}{16} - \frac{7}{8} + \frac{5}{15} \\ [/tex]
[tex] = \frac{15}{16} - \frac{14}{16} + \frac{1}{3} \\ [/tex]
[tex] = \frac{1}{16} + \frac{1}{3} \\ [/tex]
[tex] = \frac{3}{48} + \frac{16}{48} \\ [/tex]
[tex] \sf \purple {= \frac{19}{48} } \\ [/tex]

[tex] \\ \\ \\ \\ \\ \\ \\ \\ \\ [/tex]
Jawaban Nomor 3 :
[tex] \frac{1}{4} - \frac{2}{15} \times \frac{3}{18} \\ [/tex]
[tex] = \frac{1}{4} - \frac{2}{15} \times \frac{1}{6} \\ [/tex]
[tex] = \frac{1}{4 } - \frac{2}{90} \\ [/tex]
[tex] = \frac{1}{4} - \frac{1}{45} \\ [/tex]
[tex] = \frac{45}{180} - \frac{4}{180} \\ [/tex]
[tex] \tt \blue {= \frac{41}{180} } \\ [/tex]

[tex] \\ \\ \\ \\ \\ \\ \\ \\ \\ [/tex]
Jawaban Nomor 4 :
[tex] \frac{4}{7} + \frac{8}{9} \times \frac{10}{14} \\ [/tex]
[tex] = \frac{4}{7} + \frac{8}{9} \times \frac{5}{7} \\ [/tex]
[tex] = \frac{4}{7} + \frac{40}{63} \\ [/tex]
[tex] = \frac{36}{63} + \frac{40}{63} \\ [/tex]
[tex] \tt \green {= \frac{76}{63} = 1 \frac{13}{36} } \\ [/tex]

[tex] \\ \\ \\ \\ \\ \\ \\ \\ \\ [/tex]
Jawaban Nomor 5 :
[tex] \frac{8}{9} - \frac{3}{5} \div \frac{6}{5} \\ [/tex]
[tex] = \frac{8}{9} - \frac{3}{5} \times \frac{5}{6} \\ [/tex]
[tex] = \frac{8}{9} - \frac{1}{2} \\ [/tex]
[tex] = \frac{16}{18} - \frac{9}{18} \\ [/tex]
[tex] \bf \orange { = \frac{7}{18} } \\ [/tex]

Jawaban Nomor 6 :
[tex] \frac{11}{13} + \frac{9}{14} \times \frac{7}{8} \\ [/tex]
[tex] = \frac{11}{13} + \frac{9}{16} \\ [/tex]
[tex] = \frac{176}{208} + \frac{117}{208} \\ [/tex]
[tex] \tt \red { = \frac{293}{208} = 1 \frac{85}{208} } \\ [/tex]

Jawaban Nomor 7 :
[tex] \frac{7}{14} - \frac{3}{15} \times \frac{12}{24} \\ [/tex]
[tex] = \frac{1}{2} - \frac{1}{5} \times \frac{1}{2} \\ [/tex]
[tex] = \frac{1}{2} - \frac{1}{10} \\ [/tex]
[tex] = \frac{5}{10} - \frac{1}{10} \\ [/tex]
[tex] \sf \pink {= \frac{4}{10} = \frac{2}{5} } \\ [/tex]
