Tentukan hasil penjumlahan dan pengurangan pecahan di bawah ini

a.

2 frac{1}{5} + frac{5}{8} = ..... \ \ = frac{(5 times 2 + 1)}{5} + frac{5}{8} \ \ = frac{11}{5} + frac{5}{8} \ \ = frac{(40 div 5 times 11)}{40} + frac{(40 div 8 times 5)}{40} \ \ = frac{ 88 }{40} + frac{25}{40} \ \ = frac{88 + 25}{40} \ \ = frac{113}{40} \ \ = 2 frac{33}{40}

 \ \

b.

 frac{1}{6} + frac{1}{8} = ... \ \ = frac{(24 div 6 times 1)}{24} + frac{(24 div 8 times 1)}{24} \ \ = frac{4}{24} + frac{3}{24} \ \ = frac{4 + 3}{24} \ \ = frac{7}{24}

 \ \

c.

5 frac{1}{2} - 2 frac{1}{3} = ... \ \ = frac{(2 times 5 + 1)}{2} - frac{(3 times 2 + 1)}{3} \ \ = frac{11}{2} - frac{7}{3} \ \ = frac{(6 div 2 times 11)}{6} - frac{(6 div 3 times 7)}{6} \ \ = frac{33}{6} - frac{14}{6} \ \ = frac{33 - 14}{6} \ \ = frac{19}{6} \ \ = 3 frac{1}{6}

 \ \

d.

6 frac{1}{4} + 5 frac{1}{3} = .... \ \ = frac{(4 times 6 + 1)}{4} + frac{(3 times 5 + 1)}{3} \ \ = frac{25}{4} + frac{16}{3} \ \ = frac{(12 div 4 times 25)}{12} + frac{(12 div 3 times 16)}{12} \ \ = frac{75}{12} + frac{64}{12} \ \ = frac{75 + 64}{12} \ \ = frac{139}{12} \ \ = 11 frac{7}{12}
