1. 2/5 + 2 1/3 =

Penjelasan dengan langkah-langkah:

$frac{2}{5} + 2 frac{1}{3} = frac{2}{5} + frac{7}{3} = frac{6}{15} + frac{35}{15} = frac{41}{15} = 2 frac{11}{15}$

$0.8 + 20% + frac{1}{4} = frac{8}{10} + frac{20}{100} + frac{1}{4} = frac{80}{100} + frac{20}{100} + frac{25}{100} = frac{125}{100} = 1 frac{25}{100} = 1 frac{1}{4}$

2 1/3- 1 1/6 = 7/3 – 7/6 = 14/6 – 7/6= 7/6 = 1 1/6

$0.6 times frac{1}{3} times 30% = frac{6}{10} times frac{1}{3} times frac{30}{100} = frac{180}{3000} = frac{6}{100} = frac{3}{50}$

$6 div frac{1}{3} div 0.24 = frac{6}{1} div frac{1}{3} div frac{24}{100} = ( frac{6}{1} times frac{3}{1} ) div frac{24}{100} = frac{18}{1} div frac{24}{100} = frac{18}{1} times frac{100}{24} = frac{1800}{24} = 75$

semoga membantu, jangan lupa jadikan sebagai jawaban terbaik ya:)

Jawaban:

1. 2/5 + 2 1/3 =

$frac{2}{5} + frac{7}{3} \ = frac{2 times 3}{5 times 3} + frac{7 times 5}{3 times 5} \ = frac{6}{15} + frac{35}{15} \ = frac{41}{15} = 2 frac{11}{15}$

2. 0,8 + 20 % + 1/4 =

$frac{8}{10} + frac{20}{100} + frac{1}{4} \ = frac{8 times 10}{10 times 10} + frac{20 times 1}{100 times 1} + frac{1 times 25}{4 times 25} \ = frac{80}{100} + frac{20}{100} + frac{25}{100} \ = frac{125 div 25}{100 div 25} = frac{5}{4} = 1 frac{1}{4}$

3. 2 1/3 – 1 1/6 =

$2 frac{1}{3} - 1 frac{1}{6} \ = frac{3times 2 + 1}{3} - frac{6 times 1 + 1}{6} \ = frac{7 times 2}{3 times 2} - frac{7 times 1}{6 times 1} \ = frac{14}{6} - frac{7}{6} \ = frac{7}{6} \ = 1 frac{1}{6}$
