Jawaban :[tex]1) \: 2.4[/tex]
[tex] = \frac{24}{10} [/tex]
[tex] = \frac{24 \div 2}{10 \div 2} [/tex]
[tex] = \frac{12}{5} [/tex]
[tex] = \boxed{ 2 \frac{2}{5} }[/tex]
.....
[tex]2) \: 1.12[/tex]
[tex] = \frac{112}{100} [/tex]
[tex] = \frac{112 \div 4}{100 \div 4} [/tex]
[tex] = \frac{28}{25} [/tex]
[tex] = \boxed{ 1 \frac{3}{25} }[/tex]
.....
[tex]3) \: 0.35[/tex]
[tex] = \frac{35}{100} [/tex]
[tex] = \frac{35 \div 5}{100 \div 5} [/tex]
[tex] = \boxed{ \frac{7}{20} }[/tex]
.....
[tex]4) \: 0.18[/tex]
[tex] = \frac{18}{100} [/tex]
[tex] = \frac{18 \div 2}{100 \div 2} [/tex]
[tex] = \boxed{\frac{9}{50} }[/tex]
