tolong besok dikumpulin plissssss pake cara

1.
[tex] \frac{3}{8} \times \frac{4}{6} = \frac{3}{12} = \frac{1}{4} [/tex]
2.
[tex]0.2 \times 0.3 = 0.6[/tex]
3.
[tex]2.5 - \frac{3}{4} + 1 \frac{1}{2} \\ = 2.5 - 0.75 + 1.5 \\ = 3.25[/tex]
4.
[tex]10.4 - \frac{19}{5} + \frac{3}{8} \\ = \frac{104}{10} - \frac{19}{5} + \frac{3}{8} \\ = \frac{416}{40} - \frac{152}{40} + \frac{15}{40} \\ = \frac{279}{40} = 6 \frac{39}{40} [/tex]
5.
[tex]3 + 3.5 - \frac{21}{4} \\ = 3 + 3.5 - 5.25 \\ = 1.25[/tex]

Maaf jawabannya kurang jelas
