1 + 1/2 + 1/3 + 1/4 =

2 1/12
12/12+6/12+4/12+3/12
=25/12=2 1/12

samakan penyebut nya dahulu
KPK 2,3,dan 4 adalah 12
jadi
1 = [tex] \frac{12}{12} [/tex]
[tex] \frac{1}{2} = \frac{6}{12} [/tex]
[tex] \frac{1}{3} = \frac{4}{12} [/tex]
[tex] \frac{1}{4} = \frac{3}{12} [/tex]
Lalu dijumlah kan
[tex] \frac{12}{12} + \frac{6}{12} + \frac{4}{12} + \frac{3}{12} = \frac{25}{12} = 2\frac{1}{12} [/tex]
maaf kalo salah
