Tolong jawablah dengan lengakap dan peke caranya..

Jawab:

A)4/9 + 2/9 = 6/9

B)3/6 +5/6 = 8/6

C)2 1/3 + 3/4 = (2+1/3+3/4)

= (2+4/12+9/12)=(2+13/12)

=2 13/12

D)2/3+3 5/9=(3+2/3+5/9)=(3+6/9+5/9)

=(3 + 11/9) = 3 11/9

E)2/3+2 1/2+3 1/4=(2+3)+(2/3+1/2+1/4)

=(2+3)+(8/12+6/12+3/12)

=(5)+(17/12)=5 17/12

Jawaban:

$frac{4}{9} + frac{2}{9} = frac{6}{9}$

$frac{3}{6} + frac{5}{6} = frac{8}{6} = 1 frac{2}{6}$

$2 frac{1}{3} + frac{3}{4} = 2 frac{4}{12} + frac{9}{12} = 2 frac{13}{12} = 3 frac{1}{12}$

$frac{2}{3} + 3 frac{5}{9} = frac{6}{9} + 3 frac{5}{9} = 3 frac{11}{9} = 4 frac{2}{9}$

$frac{2}{3} + 2 frac{1}{2} + 3 frac{1}{4} = frac{8}{12} + 2 frac{6}{12} + 3 frac{3}{4} = 5 frac{17}{12} = 6frac{5}{12}$
