tolong jawab pake jalan​

Answer 1

Nomor 1.

[tex] \tt{ \frac{3}{2} + ( \frac{2}{5} \times \frac{3}{10} \div \frac{1}{9} ) } \\ [/tex]

[tex] \tt{ = \frac{3}{2} + ( \frac{1}{5} \times \frac{3}{5} \times \frac{9}{1} ) } \\ [/tex]

[tex] \tt{ = \frac{3}{2} + \frac{27}{25} } \\ [/tex]

[tex] \tt{ = \frac{75 + 54}{50} } \\ [/tex]

[tex] \tt \color{aqua}{ = \frac{129}{50} = 2 \frac{29}{50} } \\ [/tex]

Nomor 2.

[tex] \tt{ \frac{3}{2} - ( \frac{2}{5} \div \frac{3}{10} \times \frac{1}{9}) } \\ [/tex]

[tex] \tt{ = \frac{3}{2} - ( \frac{2}{5} \times \frac{10}{3} \times \frac{1}{9} ) } \\ [/tex]

[tex] \tt{ = \frac{3}{2} - ( \frac{2}{1} \times \frac{2}{3} \times \frac{1}{9} ) } \\ [/tex]

[tex] \tt{ = \frac{3}{2} - \frac{4}{27} } \\ [/tex]

[tex] \tt{ = \frac{81 - 8}{54} } \\ [/tex]

[tex] \tt \color{aqua}{ = \frac{73}{54} = 1 \frac{19}{54} } \\ [/tex]

Nomor 1 :

3/2 + (2/5 × 3/10 ÷ 1/9)

= 3/2 + (1/5 × 3/5 × 9/1)

= 3/2 + 27/5

= 75/50 + 54/50

= 129/50

= 2 29/50

Nomor 2 :

3/2 - (2/5 ÷ 3/10 × 1/9)

= 3/2 - (2/5 × 10/3 × 1/9)

= 3/2 - 4/27

= 81/54 - 8/54

= 73/54

= 1 19/54
