Matematika PECAHAN! JAWAB YA NO.4 JANGAN ASAL! PAKAI CARA YA KALO BISA! JAGO MATEMATIKA JAWAB INI YA!

4.1/2+9/20:15/100
10/20+9/20:15/100
19/20x100/15
19/1x5/15
19/1x1/3
19/3
6 1/3

maaf kalau salah

bismillah...
Jawab:

[tex] \frac{1}{2} + \frac{9}{20} dulu[/tex]
cari kpk, Kpk dari 2 dan 20=20.

[tex] = \frac{10}{20} + \frac{9}{20} = \frac{19}{20} [/tex]

[tex] \frac{19}{20} \div \frac{15}{100} = \frac{19}{20} \times \frac{100}{15} = \frac{1900}{300} = 6 \frac{100}{300} [/tex]
[tex] = 6 \frac{1}{3} [/tex]
atau 6,3.
Maaf kalau salah
