tolong jawab no. 3dan5 ya

No. 3

[tex]\frac{3}{4} + 1\frac{1}{2} + 1.5 \\ \\ = \frac{3}{4} + \frac{3}{2} + \frac{15}{10} \\ \\ = \frac{3\times5}{4\times5} + \frac{3\times10}{2\times10} + \frac{15\times2}{10\times2} \\ \\ = \frac{15}{20} + \frac{30}{20} + \frac{30}{20} \\ \\ = \frac{15+30+30}{20} \\ \\ = \frac{75}{20} = 3.75[/tex]

No. 5

Uang pajak:

[tex]2\frac{1}{2}\%\times1\,200\,000 = \frac{5}{200}\times1\,200\,000 = 5\times 30\,000 = 30\,000[/tex]

Biaya pendidikan

[tex]\frac{1}{5} \times 1\,200\,000 = 240\,000[/tex]

Jumlah semuanya

[tex]240\,000 + 30\,000 = 270\,000[/tex]
