Jawab:
c) 6 23/30
d) 3 16/21
e) 3 2/3
Penjelasan dengan langkah-langkah:
c) 4 3/5 + 2 1/6 = 4 18/30 + 2 5/30
= 6 23/30
d) 1 3/7 + 2 1/3 = 1 9/21 + 2 7/21
= 3 16/21
e) 3 1/6 + 2/4 = 3 2/12 + 6/12
= 3 8/12 ------> 3 2/3
Penjelasan dengan langkah-langkah:
[tex]4 \frac{3}{5} + 2 \frac{1}{6} = \frac{23}{5} + \frac{13}{6} = \frac{138 + 65}{30} = \frac{203}{30} = 6\frac{23}{30} [/tex]
[tex] 1\frac{3}{7} + 2 \frac{1}{3} = \frac{10}{7} + \frac{7}{3} = \frac{30 + 49}{21} = \frac{79}{21} = 3 \frac{16}{21} [/tex]
[tex]3 \frac{1}{6} + \frac{2}{4} = \frac{19}{6} + \frac{2}{4} = \frac{38 + 6}{12} = \frac{44}{12} = 3 \frac{8}{12} [/tex]
