Nomor 1

$frac{3}{4} - frac{1}{3} = frac{9 - 4}{12} = frac{5}{12}$

Nomor 2

$frac{5}{6} - frac{2}{5} = frac{25 - 12}{30} = frac{13}{30}$

Nomor 3

$frac{9}{10} - frac{3}{4} = frac{18 - 15}{20} = frac{3}{20}$

Nomor 4

$5 - frac{2}{3} = frac{5}{1} - frac{2}{3} = frac{15 - 2}{3} = frac{13}{3} = 4 frac{1}{3}$

Nomor 5

$7 - frac{1}{4} = frac{7}{1} - frac{1}{4} = frac{28 - 1}{4} = frac{27}{4} = 6 frac{3}{4}$

Nomor 6

$9 - frac{2}{5} = frac{9}{1} - frac{2}{5} = frac{45 - 2}{5} = frac{43}{5} = 8 frac{3}{5}$

Nomor 7

$10 - 3 frac{3}{9} = frac{10}{1} - frac{30}{9} \ = frac{90 - 30}{9} = frac{60}{9} \ = frac{20}{3} = 6 frac{2}{3}$

Nomor 8

$4 frac{3}{4} - 2 frac{1}{2} = frac{19}{4} - frac{5}{2} = frac{38 - 20}{8} \ = frac{18}{8} = frac{9}{4} = 2 frac{1}{4}$

Nomor 9

$6 frac{1}{3} - 3 frac{3}{5} = frac{19}{3} - frac{18}{5} \ = frac{95 - 54}{15} = frac{41}{15} = 2 frac{11}{15}$

Nomor 10

$frac{7}{8} - frac{1}{3} - frac{2}{6} = frac{42 - 16 - 16}{48} = frac{10}{48} = frac{5}{24}$

Nomor 11

$frac{9}{10} - frac{1}{5} - frac{1}{2} = frac{9 - 2 - 5}{10} = frac{2}{10} = frac{1}{5}$

Nomor 12

$frac{11}{12} - frac{2}{3} - frac{1}{4} = frac{11 - 8 - 3}{12} = frac{0}{12} = 0$

Nomor 13

$5 frac{5}{6} - 1 frac{1}{2} - 2 frac{1}{3} = frac{35}{6} - frac{3}{2} - frac{7}{3} \ = frac{35 - 9 - 14}{6} = frac{12}{6} = 2$

Nomor 14

$9 frac{1}{3} - frac{3}{4} - 2 frac{1}{6} = frac{28}{3} - frac{3}{4} - frac{13}{6} \ = frac{112 - 9 - 26}{12} = frac{77}{12} = 6 frac{5}{12}$

Nomor 15

$7 frac{1}{10} - 2 frac{1}{2} - 2 frac{2}{5} = frac{71}{10} - frac{5}{2} - frac{12}{5} \ = frac{71 - 25 - 24}{10} = frac{22}{10} = frac{11}{5} = 2 frac{1}{5}$

Penjelasan dengan langkah-langkah:

$1) frac{3}{4} - frac{1}{3} \ \ \ frac{9}{12} - frac{4}{12} \ \ = frac{5}{12}$

__________________________________

$2) frac{5}{6} - frac{2}{5} \ \ \ frac{25}{30} - frac{12}{30} \ \ = frac{13}{30}$

__________________________________

$3) frac{9}{10} - frac{3}{4} \ \ \ \ frac{18}{20} - frac{15}{20} \ \ \ = frac{3}{20}$

___________________________________

$4)5 - frac{2}{3} \ \ \ \ frac{15}{3} - frac{2}{3} \ \ = frac{13}{3}$

__________________________________

$5)7 - frac{1}{4} \ \ \ frac{28}{4} - frac{1}{4} \ \ = frac{27}{4}$

hanya itu yang saya tau kak
