Penjelasan dengan langkah-langkah:

$2 frac{2}{5} times 3 frac{3}{4} \ = frac{12}{5} times frac{15}{4} \ = frac{12 times 15}{5 times 4} \ = frac{180}{20} = frac{9}{1} = 9$

$2.6 times 3.15 \ = frac{26}{10} times frac{315}{100} \ = frac{26 times 315}{10 times 100} \ = frac{8190}{1000} = 8.19$

$7 frac{7}{10} div 2 frac{1}{5} \ = frac{77}{10} div frac{11}{5} \ = frac{77}{10} times frac{5}{11} \ = frac{77 times 5}{10 times 11} \ = frac{385}{110} = 3 frac{55}{110}$

$45% : dari : 2.500 \ = frac{2.500}{100} times 45 \ = 112.500 div 100 = 1.125$

11.

$2 frac{2}{9} times 3 frac{3}{5} div 1 frac{2}{5} \ = frac{20}{9} times frac{18}{5} div frac{7}{5} \ = frac{20 times 18}{9 times 5} div frac{7}{5} \ = frac{360}{45} div frac{7}{5} \ = frac{360}{45} times frac{5}{7} \ = frac{360 times 5}{45 times 7} \ = frac{1800}{315} = 5 frac{225}{315}$

12.

$0.8 times 0.5 \ = frac{8}{10} times frac{5}{10} \ = frac{8 times 5}{10 times 10} \ = frac{40}{100} = frac{2}{5}$

13.

$4 frac{1}{5} div frac{3}{5} \ = frac{21}{5} div frac{3}{5} \ = frac{21}{5} times frac{5}{3} \ = frac{105}{15} = frac{7}{1} = 7$

14.

$1.25 times frac{6}{10} \ = frac{125}{100} times frac{6}{10} \ = frac{125 times 6}{100 times 10} \ = frac{750}{1000} = 0.75$

15.

$6.5 div 2.5 \ = frac{65}{10} div frac{25}{10} \ = frac{65}{10} times frac{10}{25} \ = frac{65 times 10}{10 times 25} \ = frac{650}{250} = frac{13}{5} = 2.6$

SEMOGA BERMANFAAT
