1. tentukan perkalian berikut :

a. 8/9 × 5/4 = …
b. 2× 9/12 = …
c. 3 3/4 × 3/5 = …

2. Tentukan hasil pembagian berikut :
a. 5/9 ÷ 2/5 = …
b. 5 ÷ 9/10 = …
c. 8/9 ÷ 2 =…
d. 1 3/4 ÷ 4/9 = ….

1. tentukan perkalian berikut :

Jawaban:

no 1

$frac{8}{9} times frac{5}{9} = frac{40}{81}$

$2 times frac{9}{12} = frac{2}{1} times frac{9}{12} = frac{18}{12} = 1 frac{6}{12}$

$3 frac{3}{4} times frac{3}{5} = frac{15}{4} times frac{3}{5} = frac{45}{20} = 2 frac{5}{20}$

no 2

$frac{5}{9} div frac{2}{5} = frac{5}{9} times frac{5}{2} = frac{25}{18} = 1 frac{7}{18}$

$5 div frac{9}{10} = frac{5}{1} times frac{10}{9} = frac{50}{9} = 5 frac{5}{9}$

$frac{8}{9} div 2 = frac{8}{9} times frac{1}{2} = frac{8}{18}$

$1 frac{3}{4} div frac{4}{9} = frac{7}{4} times frac{9}{4} = frac{63}{16} = 3 frac{15}{16}$

Penjelasan dengan langkah-langkah:

1. tentukan hasil perkalian berikut :

a. 8/9 × 5/4 = 40/36

b. 2 × 9/12 = 2/1 × 9/12 = 18/12

c. 3 3/4 × 3/5 = 13/4 × 3/5 = 39/20

2. tentukan hasil pembagian berikut :

a. 5/9 ÷ 2/5 = 5/9 × 5/2 = 25/18

b. 5 ÷ 9/10 = 5/1 × 10/9 = 50/9

c. 8/9 ÷ 2 = 8/9 × 2/1 = 8/9 × 1/2 = 8/18

d. 1 3/4 ÷ 4/9 = 7/4 × 9/4 = 63/16

maaf kalo salah, semoga membantu
