Hasilnya berapa? pake cara​

Answer 1

Jawaban:

[tex]3 \frac{4}{6} + 2 \frac{3}{7} \\ mengubah \: pecahan \: campuran[/tex]

[tex]3 \frac{4}{6} = \frac{6 \times 3 + 4}{6} = \frac{22}{6} [/tex]

[tex]2 \frac{3}{7} = \frac{7 \times 2 + 3}{7} = \frac{17}{7} [/tex]

Maka :

[tex]3 \frac{4}{6} + 2 \frac{3}{7} = \frac{22}{6} + \frac{17}{7} [/tex]

Lalu menyamakan penyebut dengan mencari KPK dari 6 dan 7 yaitu, 42

[tex] \frac{22}{6} + \frac{17}{7} = \frac{154 + 102}{42} = \frac{256}{42} \\ = 6 \frac{4}{42} \\ = 6 \frac{2}{21} [/tex]

Answer 2

3 4/6 + 2 3/7

= 22/6 + 17/7

= 22(7)/6(7) + 17(6)/7(6)

= 154/42 + 102/42

= 256/42

= 128/21

= 6 2/21
