Come si scrive 0.15 come frazione?

$0.15 = \frac{3}{20}$ $0.15=3/20$

$0.15 \Leftrightarrow 0 + \frac{1}{10} + \frac{5}{100}$ $0.15hArr0+1/10+5/100$

= $\frac{1}{10} + \frac{5}{100}$ $1/10+5/100$

= $\frac{1 \times 10}{10 \times 10} + \frac{5}{100}$ $(1xx10)/(10xx10)+5/100$

= $\frac{10}{100} + \frac{5}{100}$ $10/100+5/100$

= $\frac{15}{100}$ $15/100$

= $\frac{3 \times 5}{20 \times 5}$ $(3xx5)/(20xx5)$

= $(3xxcancel5)/(20xxcancel5)$

= $3/20$
