Tolong di jawabkan pertanyaan di atas pake dengan caranya , jangan asal² an atau saya report , kalo benar saya akan kasih bintang 5 , like dan jawaban tercedas ( jika brainly sudah adakan di layar saya ) , urgent banget kumpul hari ini !!
Jawaban:
[tex]1)0,75 + \frac{2}{3} \times 8 \\ = \frac{75}{100} + \frac{2}{3} \times \frac{8}{1} \\ = \frac{75}{100} + \frac{16}{3} \\ = \frac{225}{300} + \frac{1.600}{300} \\ = \frac{1.825}{300} \\ = \frac{73}{12} \\ = 6 \frac{1}{12} [/tex]
[tex]2)( \frac{1}{6} + \frac{2}{3} ) \times ( \frac{1}{2} - \frac{1}{4}) \\ = ( \frac{1}{6} + \frac{4}{6}) \times ( \frac{2}{4} - \frac{1}{4} ) \\ = \frac{5}{6} \times \frac{1}{4} \\ = \frac{5}{24} [/tex]
[tex]3)( \frac{4}{5} - ( \frac{1}{5} - \frac{1}{2})) \times 5 \frac{1}{3} \\ = ( \frac{4}{5} - ( \frac{2}{10} - \frac{5}{10})) \times \frac{16}{3} \\ = ( \frac{4}{5} - ( - \frac{3}{10} ) \times \frac{16}{3} \\ = \frac{4}{5} + \frac{3}{10} \times \frac{16}{3} \\ = \frac{8}{10} + \frac{3}{10} \times \frac{16}{3} \\ = \frac{24}{10} \times \frac{16}{3} \\ = \frac{384}{30} \\ = \frac{128}{10} \\ = \frac{64}{5} \\ = 12 \frac{4}{5} [/tex]
[tex]4)( \frac{2}{7} + (0,5 - 0,4)) \times 3 \frac{1}{5} \\ = ( \frac{2}{7} + ( \frac{5}{10} - \frac{4}{10} )) \times \frac{16}{5} \\ =( \frac{2}{7} + \frac{1}{10} )\times \frac{16}{15} \\ =( \frac{20}{70} + \frac{7}{70} ) \times \frac{16}{5} \\ = \frac{27}{70} \times \frac{16}{5} \\ = \frac{432}{350} \\ = 1 \frac{82}{350} [/tex]
[tex]5)212,003 + ( 121,68 + 109,83 ) \\ = 212,00 3 + 231,51 \\ = 443,513[/tex]
[tex]6)(1 \frac{1}{2} + 2 \frac{3}{5} ) - 2 \frac{5}{10} \\ = ( \frac{3}{2} + \frac{13}{5} ) - \frac{25}{10} \\ = (\frac{15}{10} - \frac{26}{10} ) - \frac{25}{10} \\ = - \frac{11}{10} - \frac{25}{10} \\ = - \frac{36}{10} \\ = - \frac{18}{5} \\ = - 3 \frac{3}{5} [/tex]
