1. 2 ⅓ + 4/5 - 3/15 =...... 2. Sederhanakan 18/38 =..... 3. 6/4 + 7/4 =...... 4. 2/8 × 3 ²/4 : 4/12 =.... 5. Ratna memiliki kain 2 ²/5 m kemudian membeli lagi

1.50/15=10/3
2.9/19
3.13/4
4.336/128=21/8
5.17/20 m
mav ya kalo salah

1.
[tex]2 \frac{1}{3} + \frac{4}{5} - \frac{3}{15} = 2 \frac{5}{15} + \frac{12}{15} - \frac{3}{15} \\ = 2 \frac{17}{15} - \frac{3}{15} \\ = 2 \frac{14}{15} [/tex]
2.
[tex] \frac{18}{38} = \frac{9}{19} [/tex]
3.
[tex] \frac{6}{4} + \frac{7}{4} = \frac{13}{4} = 3 \frac{1}{4} [/tex]
4.
[tex] \frac{2}{8} \times 3 \frac{2}{4} \div \frac{4}{12} = \frac{2}{8} \times \frac{14}{4} \div \frac{4}{12} \\ = \frac{7}{8} \times \frac{12}{4} \\ = \frac{21}{8} = 2 \frac{5}{8} [/tex]
5.
[tex]2 \frac{2}{5 } + \frac{3}{4} - 2\frac{1}{4} = 2 \frac{8}{20} + \frac{15}{20} - 2 \frac{5}{20} \\ = 2 \frac{23}{20} - 2\frac{5}{20} \\ = \frac{18}{20} = \frac{9}{10} [/tex]
maaf kalau jawabannya kurang tepat
