Diketahui n-40%=8/5.Nilai n+3adalah.....
pake cara ​

Penjelasan dengan langkah-langkah:

_____________________________

Ubah ke bentuk pecahan

[tex]\boxed{\tt p\% = \frac{p}{100}}[/tex]

_____________________________

[tex]\sf n - 40 \% = \dfrac{8}{5}[/tex]

[tex]\sf n - \dfrac{40}{100} = \dfrac{8}{5}[/tex]

[tex]\sf n - \dfrac{40 \div 20}{100 \div 20} = \dfrac{8}{5}[/tex]

[tex]\sf n - \dfrac{2}{5} = \dfrac{8}{5}[/tex]

[tex]\sf n = \dfrac{8}{5} + \dfrac{2}{5}[/tex]

[tex]\sf n = \dfrac{8 + 2}{5}[/tex]

[tex]\sf n = \dfrac{10}{5}[/tex]

[tex]\sf n = 2[/tex]

_____________________________

Nilai n + 3

= n + 3

= 2 + 3

= 5
