- Jawab:
[tex] \boxed{a.} \: \: \frac{1}{5} = \frac{1}{5} \times 100\% = \bf20\%[/tex]
[tex] \boxed{b.} \: \: \frac{31}{50} = \frac{31}{50} \times 100\% = \bf62\%[/tex]
[tex] \boxed{c.} \: \: \frac{13}{20} = \frac{13}{20} \times 100\% = \bf65\%[/tex]
Penjelasan dengan langkah-langkah:
Cara lebih rinci :
a.
[tex] \frac{1}{5} = \frac{1}{5} \times 100\% = \frac{100}{5} = \bf20\%[/tex]
b.
[tex] \rm \frac{31}{ 50} = \frac{31}{ \cancel{50}} \times \cancel{100}\% = 31 \times 2 = \bf62\%[/tex]
*100 dan 50 dicoret artinya dibagi
(100 : 50 = 2)
c.
[tex] \rm \frac{13}{ 20} = \frac{13}{ \cancel{20}} \times \cancel{100}\% = 13 \times 5 = \bf65\%[/tex]
*100 dan 20 dicoret artinya dibagi
(100 : 20 = 5)
