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]

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]
