A.8/9×5/4=b.8× 9/12=a.5/9:2/5=b.5 :9/10=​

Jawaban:

8/9×5/4=

40/36=

1 4/36=

1 1/9

8× 9/12=

72/12=

6

5/9:2/5=

25/18=

1 7/18

5 :9/10 =

50/9=

5 5/9

Jawaban:

a. 8/9 × 5/4 = 40/36 = 1 1/9

b. 8 × 9/12 = 72/12 = 6/1

a. 5/9 ÷ 2/5 = 25/18 = 1 7/18

b. 5 ÷ 9/10 = 50/9 = 5 5/9

Penjelasan dengan langkah-langkah:

8/9 × 5/4

= 8×5/9×4

= 40/36

setelah didapatkan hasilnya, disederhanakan

40/36 = 20/18 = 10/9 = 1 1/9

——————–

8 × 9/12

= 8/1 × 9/12

= 8×9/1×12

= 72/12

disederhanakan menjadi:

72/12 = 6/1

——————–

5/9 ÷ 2/5

= 5/9 × 5/2

= 5×5/9×2

= 25/18

disederhanakan

25/18 = 1 7/18

——————–

5 ÷ 9/10

= 5/1 ÷ 9/10

= 5/1×10/9

= 5×10/1×9

= 50/9

disederhanakan

50/9 = 5 5/9
