Jawaban b :
[tex] \frac{4}{5} \times 1 \frac{2}{3} = \frac{4}{5} \times \frac{5}{3} = \frac{20 \div 5}{15 \div 5} = \frac{4}{3} = 1 \frac{1}{3} [/tex]
Jawaban c :
Ubah desimal kepecahan :
[tex]15,25 = \frac{1.525}{100} = \frac{1.525 \div 25}{ 100\div25 } = \frac{61}{4} [/tex]
Jadi :
[tex] \frac{61}{4} \div \frac{5}{16} = \frac{61}{4} \times \frac{16}{5} = \frac{976 \div 4}{20 \div 4} = \frac{244}{5} = 48 \frac{4}{5} [/tex]
Penjelasan dengan langkah-langkah:
Nomor B :
[tex] \frac{4}{5} \times 1 \frac{2}{3} [/tex]
[tex] = \frac{4}{5} \times \frac{5}{3} [/tex]
[tex] = \frac{20}{15} = \frac{4}{3} [/tex]
Nomor C :
[tex]15.25 \div \frac{5}{16} [/tex]
[tex] = \frac{1525}{100} \div \frac{5}{16} [/tex]
[tex] = \frac{1525 \times 16}{100 \times 5} [/tex]
[tex] = \frac{24.400}{500} [/tex]
[tex] = 48 \frac{400}{500} = 48 \frac{4}{5} [/tex]
