H. 91/24 atau 3 19/24
i. 227/40 atau 5 27/40
Penjelasan dengan langkah-langkah:
- F .
[tex] \frac{4}{5} + 2 \frac{1}{4} = [/tex]
[tex] \frac{4}{5} + \frac{2 \times 4 + 1}{4} = [/tex]
[tex] \frac{4}{5} + \frac{9}{4} = [/tex]
DISAMAKAN BAWAHNYA
[tex] \frac{4 \times 4}{5 \times 4} + \frac{9 \times 5}{4 \times 5} [/tex]
[tex] \frac{16}{20} + \frac{45}{20} = [/tex]
[tex] \frac{16 + 45}{20} = \frac{61}{20} |3 \frac{1}{20} [/tex]
- G .
[tex] 1\frac{5}{7} + 2 \frac{2}{3} = [/tex]
[tex] \frac{1 \times 7 + 5}{7} + \frac{2 \times 3 + 2}{3} = [/tex]
[tex] \frac{12}{7} + \frac{8}{3} = [/tex]
DISAMAKAN BAWAHNYA
[tex] \frac{12 \times 3}{7 \times 3} + \frac{8 \times 7}{3 \times 7} = [/tex]
[tex] \frac{36}{21} + \frac{56}{21} = [/tex]
[tex] \frac{36 + 56}{21} = \frac{92}{21} |4 \frac{8}{21} [/tex]
- H .
[tex] 2 \frac{5}{8} + 1 \frac{1}{6} [/tex]
[tex] \frac{2 \times 8 + 5}{8} + \frac{1 \times 6 + 1}{6} = [/tex]
[tex] \frac{21}{8} + \frac{7}{6} = [/tex]
DISAMAKAN BAWAHNYA
[tex] \frac{21 \times 3}{8 \times 3} + \frac{7 \times 4}{6 \times 4} = \frac{63}{24} + \frac{28}{24} = [/tex]
[tex] \frac{63 + 28}{24} = \frac{91}{24} |3 \frac{19}{24} [/tex]
- i .
[tex] 3\frac{3}{10} + 2 \frac{3}{8} [/tex]
[tex] \frac{3 \times 10 + 3}{10} + \frac{2 \times 8 + 3}{8} = \frac{33}{10} + \frac{21}{8} = [/tex]
DISAMAKAN BAWAHNYA
[tex] \frac{33 \times 4}{10 \times 4} + \frac{19 \times 5}{8 \times 5} = \frac{132}{40} + \frac{95}{40} [/tex]
[tex] \frac{132 + 95}{40} = \frac{227}{40} |5 \frac{27}{40} [/tex]
