[tex]4 \frac{2}{5} - 1 \frac{1}{3} + 2 \frac{3}{4} [/tex]
temukan hasil penjumlahan tersebut pakai jalan!!
[tex] \frac{7}{30} + \frac{3}{20} -4 \frac{1}{4} [/tex]
temukan hasil penjumlahan tersebut pakai jalan!!
Jawaban:
[tex]2 \frac{1}{3} + \frac{3}{4} = \frac{7}{3} + \frac{3}{4} \\ \: \: \: \: \: = \frac{28}{12} + \frac{9}{12} \\ = \frac{37}{12} = 3 \frac{1}{12} [/tex]
[tex]4 \frac{2}{5} - 1 \frac{1}{3} + 2 \frac{3}{4} \\ \frac{22}{5} - \frac{4}{3} + \frac{11}{4} = \frac{264}{60} - \frac{80}{60} + \frac{165}{60} \\ = \frac{ 349}{60} = 5 \frac{49}{60} [/tex]
[tex] \frac{7}{30} + \frac{3}{20} - 4 \frac{1}{4} \\ \frac{7}{30} + \frac{3}{20} - \frac{17}{4} = \frac{14}{60} + \frac{9}{60} - \frac{255}{60} \\ = - \frac{232}{60} [/tex]
semoga membantu
