Jawaban:
1.
[tex]9 \frac{3}{4} \: kg[/tex]
2.
[tex]1 \frac{1}{3} kg[/tex]
3.
[tex]7 \frac{33}{40} m[/tex]
4.
[tex] 1\frac{8}{15} kg[/tex]
5.
[tex]4.5 \: kg[/tex]
Penjelasan dengan langkah-langkah:
1.
[tex]4 \frac{1}{2} + 5 \frac{1}{4} = \frac{9}{2} + \frac{21}{4} = \\ = \frac{18 + 21}{4} = \frac{39}{4} = 9 \frac{3}{4} kg[/tex]
2.
[tex] \frac{13}{15} + \frac{7}{15} = \frac{20}{15} \\ \frac{20}{15} = 1 \frac{5}{15} kg = 1 \frac{1}{3} kg[/tex]
3.
[tex]3 \frac{5}{8} + 4 \frac{1}{5} = \frac{29}{8} + \frac{21}{5} \\ = \frac{145 + 168}{40} = \frac{313}{40} \\ \frac{313}{40} = 7 \frac{33}{40} m[/tex]
4.
[tex] \frac{5}{6} + \frac{7}{10} = \frac{25 + 21}{30} \\ = \frac{46}{30}kg \\ \frac{46}{30} = 1 \frac{16}{30} = 1 \frac{8}{15} kg[/tex]
5.
[tex]2.8 + 1.7 = 4.5 \: kg[/tex]
