1. 1,5+2/5-0,3×1/9=
2. 0,5+⅓:0,2=
tolong pakai jalan ya kakak​

Answer 1

Nomor 1.

Kerjakan dahulu perkaliannya

[tex] \tt \color{b8ecbe}{1.5 + \frac{2}{5} - (0.3 \times \frac{1}{9}) } \\ [/tex]

[tex] \tt \color{92ecce}{ = \frac{15}{10} + \frac{2}{5} - ( \frac{3}{10} \times \frac{1}{9} )} \\ [/tex]

[tex] \tt \color{74e8e6}{ = \frac{3}{2} + \frac{2}{5} - ( \frac{1}{10} \times \frac{1}{3} )} \\ [/tex]

[tex] \tt \color{7cdffe}{ = \frac{3}{2} + \frac{2}{5} - \frac{1}{30} } \\ [/tex]

[tex] \tt \color{a6cfff}{ = \frac{45 + 12 - 1}{30} } \\ [/tex]

[tex] \tt \color{d8baff}{ = \frac{56}{30} = \frac{28}{15} = 1 \frac{13}{15} } \\ [/tex]

Nomor 2.

Kerjakan dahulu pembagiannya

[tex] \tt \color{ffa5ff}{0.5 + ( \frac{1}{3} \div 0.2)} \\ [/tex]

[tex] \tt \color{d8baff}{ = \frac{5}{10} + ( \frac{1}{3} \div \frac{2}{10}) } \\ [/tex]

[tex] \tt \color{a6cfff}{ = \frac{1}{2} + ( \frac{1}{3} \div \frac{1}{5} )} \\ [/tex]

[tex] \tt \color{7cdffe}{ = \frac{1}{2} + ( \frac{1}{3} \times \frac{5}{1} )} \\ [/tex]

[tex] \tt \color{74e8e6}{ = \frac{1}{2} + \frac{5}{3} } \\ [/tex]

[tex] \tt \color{92ecce}{ = \frac{ 3 + 10}{6} } \\ [/tex]

[tex] \tt \color{b8ecbe}{ = \frac{13}{6} = 2 \frac{1}{6} } \\ [/tex]

Semoga membantu

Penjelasan dengan langkah-langkah:

Nomor 1 :

1.5 + 2/5 - (0.3 × 1/9)

= 15/10 + 2/5 - (3/10 × 1/9)

= 3/2 + 2/5 - (1/10 × 1/3)

= 3/2 + 2/5 - 1/30

= 45/30 + 12/30 - 1

= 56/30

= 28/15

= 1 13/15

Nomor 2 :

0.5 + (1/3 ÷ 0,2)

= 5/10 + (1/3 ÷ 2/10)

= 1/2 + (1/3 ÷ 1/5)

= 1/2 + 5/3

= 3/6 + 10/6

= 13/6

= 2 1/6
