makasih yg jawab​

Answer 1

Nomor 1

Kakak : adik = 10 : 8

Selisih usia = 4

Usia kakak

[tex] = \frac{10}{10 - 8} \times 4[/tex]

[tex] = \frac{10}{2} \times 4[/tex]

[tex] = 5 \times 4[/tex]

[tex] = 20[/tex]

Usia adik

[tex] = \frac{8}{10 - 8} \times 4[/tex]

[tex] = \frac{8}{2} \times 4[/tex]

[tex] = 4 \times 4[/tex]

[tex] = 16[/tex]

[tex] \\ [/tex]

Nomor 2

[tex]1 \frac{2}{3} + \frac{3}{4} \times 1 \frac{2}{5} \div \frac{1}{2} [/tex]

[tex] = \frac{5}{3 } + \frac{3}{4} \times \frac{7}{5} \div \frac{1}{2} [/tex]

[tex] = \frac{5}{3} + \frac{3}{4} \times \frac{7}{5} \times \frac{2}{1} [/tex]

[tex] = \frac{5}{3} + \frac{42}{20} [/tex]

[tex] = \frac{5}{3} + \frac{21}{10} [/tex]

[tex] = \frac{50 + 63}{30} [/tex]

[tex] = \frac{113}{30} [/tex]

[tex] = 3 \frac{23}{30} [/tex]
