NOMOR 4.

[tex]4 \frac{3}{8} \times 4 \frac{4}{5} = \frac{(4 \times 8 + 3)}{8} \times \frac{(4 \times 5 + 4)}{5} [/tex]

[tex]= \frac{35}{8} \times \frac{24}{5} = \frac{35 \times 24}{8 \times 5} = \frac{840}{40} = 21[/tex]

NOMOR 5.

[tex]4 \frac{2}{4} \times 2 \frac{5}{6} = \frac{(4 \times 4 + 2)}{4} \times \frac{(2 \times 6 + 5)}{6} [/tex]

[tex]= \frac{18}{4} \times \frac{17}{6} = \frac{18 \times 17}{4 \times 6} = \frac{306}{24} = \frac{51}{4} = 12 \frac{3}{4} [/tex]
