4.7 5/10 - 0,5 x 2½=
5.30% x 20.000 - ½ x 30.000
tolong jawab ke pecahan biasa ya kakak kakak
anw, nomor 3 itu lima, enam per tujuh
Penjelasan dengan langkah-langkah:
[tex]1). \: \frac{2}{5} + \frac{3}{4} - \frac{1}{3} = \frac{24 + 45 - 20}{60} = \frac{49}{60} \\ 2). \: 3 \frac{3}{4} \div \frac{1}{4} \times 2 = 15 \times 2 = 30 \\ 3). \: 5 \frac{6}{7} + 2 \frac{1}{3} = (5 + 2) + ( \frac{6}{7} + \frac{1}{3} ) \\ = 7 + ( \frac{18 + 7}{21} ) \\ = 7 + \frac{25}{21} = 7 + 1 \frac{4}{21} = 8 \frac{4}{21} \\ 4). \: 7 \frac{5}{10} - 0.5 \times 2 \frac{1}{2} = 7 \frac{5}{10} - \frac{1}{2} \times 2 \frac{1}{2} \\ = 7 \frac{5}{10} - ( \frac{1}{2} \times 2 \frac{1}{2} ) \\ = 7 \frac{5}{10} - ( \frac{1}{2} \times \frac{5}{2}) \\ = 7 \frac{5}{10} - ( \frac{1 \times 5}{2} ) \\ = 7 \frac{5}{10} - \frac{5}{2} = 7 \frac{5}{10} - 2 \frac{1}{2} \\ = (7 - 2)( \frac{5}{10} - \frac{1}{2} ) \\ = 5( \frac{5 - 1}{10} ) = 5 \frac{4}{10} = 5 \frac{2}{5}[/tex]
[tex]5).30\% \times 20.000 - \frac{1}{2} \times 30.000 \\ = ( \frac{30}{100} \times 20.000) - ( \frac{1}{2} \times 30.000) \\ = 6.000 - 15.000 \\ = - 9000[/tex]
