21/3-33/461/4-32/52/3+1/55/9+3/42/3+4/9

Jawaban:

21/3 – 33/4 = $8 frac{81}{12}$

61/4-32/5 = 177/20 atau

$8 frac{17}{20}$

2/3+1/5 = 13/15

5/9+3/4 = 47/36

$1 frac{11}{36}$

2/3+4/9 = 10/9

$1 frac{1}{9}$

Penjelasan dengan langkah-langkah:

$frac{21}{3} - frac{33}{4} = frac{84}{12} - frac{3}{12} = 8 frac{81}{12} : atau : 14 frac{9}{12}$

$frac{61}{4} - frac{32}{5} = frac{305}{20} - frac{128}{20} = frac{177}{20} : atau : 8 frac{17}{20}$

$frac{2}{3} + frac{1}{5} = frac{6}{9} + frac{4}{9} = frac{10}{9} : atau : 1 frac{1}{9}$

$frac{5}{9} + frac{3}{4} = frac{20}{36} + frac{27}{36} = frac{47}{36} : atau : 1 frac{11}{36}$
