$bf1 frac{1}{2} div 0, 5 = frac{3}{2} div frac{5}{cancel10} = frac{3}{cancel2} times frac{10}{5} = frac{3}{1} times frac{cancel5}{cancel5} = frac{3}{1} = 3$

No. 2

$bf4, 5 times 1, 5 = frac{cancel45}{cancel10} times frac{bcancel15}{bcancel10} = frac{9}{2} times frac{3}{2} = frac{27}{4} = 6 frac{3}{4}$

$boxed{ sf{A: n: s : w : e : r : : by : : }{ boxed{ green{ sf{ DGFC }}}}}$

Penjelasan dengan langkah-langkah:

Operasi Hitung Pecahan

a/b : c/d = a/b × d/c

a/b × c/d = (a × c)/(b × d)

…

maka,

1).

= 1 ½ : 0,5

= 3/2 : 5/10

= 3/2 : 1/2

= 3/2 × 2/1

= 6/2

= 3

….

2).

= 4,5 × 1,5

= 45/10 × 15/10

= 9/2 × 3/2

= 27/4

atau

= 6,75
