Hasil dari 7,5-25% +1 2/5 =

Jawaban:

= 7,5 – 25% + 1 2/5

= 75/10 – 25/100 + 7/5

= 750/100 – 25/100 + 140/100

= 725/100 – 140/100

= 585/100

= 5 85/100

= 5 17/20

Penjelasan dengan langkah-langkah:

$7.5 - 25% + 1 frac{2}{5 } = \ frac{75}{10} - frac{25}{100} + 1 frac{2}{5} = \ frac{75}{10} - frac{1}{4} + 1frac{2}{5} = \ frac{75 times 2}{10 times 2} - frac{1 times 5}{4 times 5} + 1 frac{2 times 4}{5 times 4} = \ 1frac{150 - 5 + 8}{20} = 1 frac{153}{20} = 8 frac{13}{20}$
