2/3 × (0,72 ÷ 12/15) + 3 - 5/10

2/3 × (0,72 ÷ 12/15) + 3 – 5/10

Jawaban:

$frac{2}{3} times (0.72 div frac{12}{5} ) + 3 - frac{5}{10} = 2 frac{7}{10}$

Penjelasan:

$0.72 div frac{12}{5} = frac{360}{1200} = frac{3}{10}$

$frac{2}{3} times frac{3}{10} = frac{2 times 3}{3 times 10} = frac{6}{30} = frac{1}{5}$

$frac{1}{5} + 3 = frac{16}{5} = 3 frac{1}{5}$

$3 frac{1}{5} - frac{5}{10} = 3 frac{1}{5} - frac{1}{2} = frac{16}{5} - frac{1}{2} = frac{2 times 15 - 5 times 1}{10} = frac{27}{10} = 2 frac{7}{10}$

Maaf kalau salah
