1 2/3 x (2+1/4):0,3tolong banget ​

Saya kerjakan yang ada di dalam kurung dulu :

2 + frac{1}{4} = frac{2}{1} + frac{1}{4} = frac{8 + 1}{4} = frac{9}{4}

Saya ubah pecahan campuran dan desimalnya :

1 frac{2}{3} = frac{5}{3} \ \ 0.3 = frac{3}{10}

Lalu, hitung :

 frac{5}{3} times frac{9}{4} div frac{3}{10} \ \ = frac{5}{3} times frac{9}{4} times frac{10}{3} = frac{450}{36} = frac{25}{2} = 12 frac{1}{2}

Atau dalam desimal :

12 frac{1 times 5}{2 times 5} = 12 frac{5}{10} = 12.5

Jawaban:

1 frac{2}{3} times 2 frac{1}{4} div 0.3 = \ \ = 1 frac{2}{3} times 2 frac{1}{4} = frac{5}{3} times frac{9}{4} = frac{5 times 9}{3 times 4} = frac{45}{12} \ \

Lanjutannya Di Bawah yaa

 frac{45}{12} div 0.3 = frac{45}{12} div frac{3}{10} = frac{45}{12} times frac{10}{3} \ \ = frac{45 times 10}{12 times 3} = frac{450}{36} = 12 frac{18}{36} = 12 frac{1}{2}
