Jawaban:
a. 1 7/8
[tex] \frac{5}{8} + \frac{1}{2} = 1\frac{1}{2} + \frac{3}{4} = \frac{1 \times 8 + 1}{8} + \frac{3}{4} = \frac{9}{8} + \frac{3}{4} = \frac{9 \times 1}{8} + \frac{3 \times 2}{8} = \frac{9}{8} + \frac{6}{8} \frac{(9 + 6)}{8} = \frac{15}{8} = \frac{1 \times 8 + 7}{8} = 1\frac{7}{8} [/tex]
[tex] \frac{5}{8} + \frac{1}{2} + \frac{3}{4} [/tex]
[tex] = \frac{5 + 4 + 6}{8} [/tex]
[tex] = \frac{15}{8} [/tex]
[tex] = 1 \frac{7}{8} [/tex]
