kak tolong banget di jawab pakai cara cara
semoga membantuu yaa^^
Jawaban:
[tex]1. \: \frac{5}{6} + \frac{5}{12} = \frac{10}{12} + \frac{5}{12} = \frac{15}{12} = \frac{5}{4} [/tex]
[tex]2. \: 2 \frac{1}{6} + \frac{7}{8} = \frac{13}{6} + \frac{7}{8} = \frac{52}{24} + \frac{21}{24} \\ =\frac{73}{ 24} = 3\frac{1}{24} [/tex]
[tex]3. \: \: \frac{4}{9} +4\frac{5}{12} = \frac{4}{9} + \frac{53}{12} \\ = \frac{16}{36} + \frac{159}{36} = \frac{175}{36} = 4 \frac{31}{36} [/tex]
[tex]4. \: \: 5 \frac{3}{4} + 2 \frac{1}{8} = \frac{23}{4} + \frac{17}{8} \\ = \frac{94}{16} + \frac{34}{16} = \frac{128}{16} = 8[/tex]
[tex]4 \frac{7}{12} + 2 \frac{3}{4} = \frac{55}{12} + \frac{11}{4} \\ = \frac{55}{12} + \frac{33}{12} = \frac{88}{12} = 7 \frac{4}{12} [/tex]
