Jawaban:
1. 5 3/21 + 9/21
= 5 12/21 = 5 4/7
2. 27/24 - 7/24 = 20/24 = 5/6
Jawaban:
[tex] 1. \: 2 \frac{1}{7} + 3 \frac{9}{21} [/tex]
[tex] = \frac{15}{7} + \frac{24}{7} [/tex]
[tex] = \frac{37}{7} \: atau \: 5\frac{4}{7} [/tex]
[tex]2. \: 5 \frac{1}{8} - 4 \frac{7}{24} [/tex]
[tex] = \frac{41}{8} - \frac{103}{24} [/tex]
[tex] = 41 \times 3 \\ \: \: \: \: \: - - - \: - \frac{103}{24} \\ 8 \times 3[/tex]
[tex] = \frac{123}{24} - \frac{103}{24} [/tex]
[tex] = \frac{20}{24} [/tex]
[tex]hasil \: = \frac{5}{6} \: atau \: 0.83[/tex]
