Hanya no mer 1 kok jam 8 harus sudah di kumpulkan

a. $frac{1}{8} +frac{3}{4} =frac{1}{8} +frac{(3times2)}{8} = frac{1}{8} +frac{6}{8} =frac{7}{8}$

b. $frac{3}{5} +frac{1}{2} =frac{(3times2)}{10} +frac{(1times5)}{10} = frac{6}{10} +frac{5}{10} =frac{11}{10}$

c. $frac{1}{6} +frac{1}{4} =frac{(1times2)}{12} +frac{(1times3)}{12} = frac{2}{12} +frac{3}{12} =frac{5}{12}$

d. $frac{2}{9} +frac{1}{2} =frac{(2times2)}{18} +frac{(1times9)}{18} = frac{4}{18} +frac{9}{18} =frac{13}{18}$

e. $1frac{2}{3} +frac{5}{6} =frac{5}{3}+frac{5}{6}= frac{(5times2)}{6} +frac{5}{6} = frac{10}{6} +frac{5}{6} =frac{15}{6}=2frac{1}{2}$

f. $frac{4}{5} +2frac{1}{4} =frac{4}{5}+frac{9}{4}= frac{(4times4)}{20} +frac{(9times5)}{20} = frac{16}{20} +frac{45}{20} =frac{61}{20}=3frac{1}{20}$

Semoga dapat membantu 🙂

1a. $frac{1}{8}$ + $frac{3}{4}$ = $frac{1}{8}$ + $frac{6}{8}$ = $frac{7}{8}$

1b. $frac{3}{5}$ + $frac{1}{2}$ = $frac{5}{10}+frac{6}{10}$ = $frac{11}{10}$

1c. $frac{1}{6}$ + $frac{1}{4}$ = $frac{4}{24}+frac{6}{24}$ = $frac{10}{24}$

1d. $frac{2}{9}$ + $frac{1}{2}$ = $frac{4}{18}+frac{9}{18}$ = $frac{13}{18}$

1e. $1frac{2}{3}$ + $frac{5}{6}$ = $frac{5}{3}+frac{5}{6}$ = $frac{10}{6}+frac{5}{6}$ = $frac{15}{6}$

1f. $frac{4}{5}$ + $2frac{1}{4}$ = $frac{4}{5}+frac{9}{4}$ = $frac{16}{20}+frac{45}{20}$ = $frac{61}{20}$
