tolong dijawab sama penjelasannya
Jawaban:
1.
[tex]2 \frac{2}{4} + 3 \frac{1}{2} = \frac{5}{2} + 3 \frac{1}{2} = \frac{5}{2} + \frac{7}{2} = 6[/tex]
2.
[tex]1 \frac{1}{2} - \frac{2}{10} = \frac{3}{2} - \frac{2}{10} = \frac{3}{2} - \frac{1}{5} = \frac{3 \times 5}{2 \times 5} - \frac{1 \times 2}{5 \times 2} = \frac{15}{10} - \frac{2}{10} = \frac{15 - 2}{10} = \frac{13}{10} = 1 \frac{3}{10} = 1.3[/tex]
3.
[tex]1 \frac{1}{4} + 3 \frac{3}{5} = \frac{5}{4} + 3 \frac{3}{5} = \frac{5}{4} + \frac{18}{5} = \frac{97}{20} = 4 \frac{17}{20} = 4.85[/tex]
4.
[tex]5 - \frac{5}{10} = \frac{50}{10} - \frac{5}{10} = \frac{9}{2} = 4 \frac{1}{2} = 4.5[/tex]
