Pakai cara ya kak!

Penjelasan dengan langkah-langkah:

$1.) \ = 3 times 5.5 - 9 frac{3}{5} \ = (3 times frac{55}{10} ) - frac{48}{5} \ = (3 times frac{11}{2} ) - frac{48}{5} \ = frac{33}{2} - frac{48}{5} \ = frac{165 - 96}{10} \ = frac{69}{10} \ = 6 frac{9}{10}$

$2.) \ = 7 frac{1}{5} times 5.65 \ = frac{36}{5} times frac{565}{100} \ = frac{36}{5} times frac{113}{20} \ = frac{9}{5} times frac{113}{5} \ = frac{1017}{25} \ = 40 frac{17}{25}$

$3.) \ = 3 times 0.75 - 1.2 \ = (3 times frac{75}{100} ) - frac{12}{10} \ = (3 times frac{3}{4} ) - frac{6}{5} \ = frac{9}{4} - frac{6}{5} \ = frac{45 - 24}{20} \ = frac{21}{20} \ = 1 frac{1}{20}$

$4.) \ = 36 frac{2}{5} - 3 frac{16}{25} \ = frac{182}{5} - frac{91}{25} \ = frac{910 - 91}{25} \ = frac{819}{25} \ = 32 frac{19}{25}$

$5.) \ = 350 - frac{5}{7} \ = frac{2450 - 5}{7} \ = frac{2445}{7} \ = 349 frac{2}{7}$
