A,8/10 b,7/12,c 9/10,d 20/4 e,14/20 jadikan persen kaka” tolong ya sma langkah nya

Jawaban:

Soal A.

$frac{8}{10} times frac{10}{10} = frac{80}{100} \ = 80%$

Soal B (ini aku kurang yakin)

$frac{7}{12} times frac{8.3}{8.3} = frac{58.1}{100} \ = 58.1% = 58%$

Soal C

$frac{9}{10} times frac{10}{10} \ = frac{90}{100} \ = 90%$

Soal D

$frac{20}{4} times frac{25}{25} = frac{500}{100} = 500%$

kalo pecahan biasanya 5

Soal E

$frac{14}{20} times frac{5}{5} \ = frac{70}{100} \ = 70%$

SEMOGA BERMANFAAT^^

Jawaban :

A . 8/10 = 8/10 x 10/10

= 80/100

= 80%

B . 7/12 = 7/12 x 100

= 700/12

= 58,3%

C . 9/10 = 9/10 x 10/10

= 90/100

= 90%

D . 20/4 = 20/4 x 25/25

= 500/100

= 500%

E . 14/20 = 14/20 x 5/5

= 70/100

= 70%
