pakai cara nya
Jawab:
Nomor 1:
[tex]23.125 \times 1.7 = \frac{23125}{1000} \times \frac{17}{10} = \frac{393125}{10000} = 39.3125[/tex]
Nomor 2:
[tex]23.125 + 1.7 = \frac{23125}{1000} + \frac{17}{10} = \frac{23125}{1000} + \frac{17 \times 100}{10 \times 100} = \frac{231 25}{1000} + \frac{1700}{1000} = \frac{23125 + 1700}{1000} = \frac{24825}{1000} = 24.825[/tex]
Nomor 3:
[tex] (\frac{1}{2} \times \frac{2}{3} ) + \frac{4}{3} = \frac{1 \times 2}{2 \times 3} + \frac{4}{3} = \frac{2}{6} + \frac{4}{3} = \frac{2}{6} + \frac{4 \times 2}{3 \times 2} = \frac{2}{6} + \frac{8}{6} = \frac{2 + 8}{6} = \frac{10}{6} = \frac{10 \div 2}{6 \div 2} = \frac{5}{3} [/tex]
Nomor 4:
[tex](1 + \frac{2}{3} ) \times \frac{1}{2} \div \frac{2}{3} = ( \frac{1}{1} + \frac{2}{3} ) \times \frac{1}{2} \div \frac{2}{3} = ( \frac{1 \times 3}{1 \times 3} + \frac{2}{3} ) \times \frac{1}{2} \div \frac{2}{3} = ( \frac{3}{3} + \frac{2}{3} ) \times \frac{1}{2} \div \frac{2}{3} = \frac{5}{3} \times \frac{1}{2} \div \frac{2}{3} = \frac{5}{3} \times \frac{1}{2} \times \frac{3}{2} = \frac{15}{12} = \frac{5}{4} [/tex]
