Penjelasan dengan langkah-langkah:

= 35/6 + 5/2

= 35/6 + 15/6

= 50/6

= 25/3

Jawaban:

$3. : 5 frac{5}{6} + 2 frac{1}{2} \ = frac{35}{6} + frac{5}{2} \ = frac{35 times 1}{6 times 1} + frac{5 times 3}{2 times 3} \ = frac{35}{6} + frac{15}{6} \ = frac{50}{6} \ = 8 frac{2}{6} \ = 8 frac{ 1}{3}$

$4. : 2 frac{1}{2} + 25% \ = frac{5}{2} + frac{25}{100} \ = frac{5}{2} + frac{1}{4} \ = frac{5 times 2}{2 times 2} + frac{1}{4} \ = frac{10}{4} + frac{1}{4} \ = frac{11}{4} \ = 2 frac{3}{4}$

$5. : 4 frac{1}{4} + 2.75 \ = frac{17}{4} + frac{275}{100} \ = frac{17}{4} + frac{11}{4} \ = frac{28}{4} = 7$

$6. : 0.12 + 1.2 \ = 1.32 \ = 1 frac{32}{100} \ = 1 frac{8}{25}$

$7. : 25.25 + 2.52 \ = 27.77 \ = 27 frac{77}{100}$

$8. : 5 frac{5}{6} - 2 frac{1}{2} \ = frac{35}{6} - frac{5}{2} \ = frac{35}{6} - frac{15}{6} \ = frac{20}{6} \ = 3 frac{2}{6} \ = 3 frac{1}{3}$

$9. : 10 - frac{3}{5} \ = 10 - frac{6}{10} \ = 10 - 0.6 \ = 9.4 \ = 9 frac{4}{10} \ = 9 frac{2}{5}$

$10. : 15 - 2 frac{4}{7} \ = 15 - frac{18}{7} \ = frac{15 times 7}{1 times 7} - frac{18}{7} \ = frac{105}{7} - frac{18}{7} \ = frac{87}{7} \ = 12 frac{3}{7}$
