1).

$frac{4}{5} + frac{3}{4} = frac{16}{20} + frac{15}{20} = frac{31}{20} = 1 frac{11}{20}$

2).

$frac{2} {7} + frac{1}{4} = frac{8}{28} + frac{7}{28} = frac{15}{28}$

3).

$frac{2}{5} + frac{5}{8} = frac{16}{40} + frac{25}{40} = frac{41}{40} = 1 frac{1}{40}$

4).

$frac{5}{6} + frac{2}{7} = frac{35}{42} + frac{12}{42} = frac{47}{42} = 1 frac{5}{42}$

5).

$frac{5}{7} + frac{4}{9} = frac{45}{63} + frac{28}{63} = frac{73}{63} = 1 frac{10}{63}$

1. Hasilnya adalah 31/20 atau 1 11/20

$1.frac{4}{5} + frac{3}{4} = frac{16}{20} + frac{15}{20} = frac{31}{20} = 1 frac{11}{20}$

2. Hasilnya adalah 15/28

$2. frac{2}{7} + frac{1}{4} = frac{8}{28} + frac{7}{28} = frac{15}{28}$

3. Hasilnya adalah 41/40 atau 1 1/40

$3. frac{2}{5} + frac{5}{8} = frac{16}{40} + frac{25}{40} = frac{41}{40} = 1 frac{1}{40}$

4. Hasilnya adalah 47/42 atau 1 5/42

$4. frac{5}{6} + frac{2}{7} = frac{35}{42} + frac{12}{42} = frac{47}{42} = 1 frac{5}{42}$

5. Hasilnya adalah 73/63 atau 1 10/63

$5. frac{5}{7} + frac{4}{9} = frac{45}{63} + frac{28}{63} = frac{73}{63} = 1 frac{10}{63}$
