Jawaban :

– Chilla = 20

– Suka = 25

– Daniel = 10

– Chilla + suka + Daniel = 55

Penjelasan dengan langkah – langkah penyelesaian :

5 × Chilla : 10 = 10

suka × 4 : 5 = 20

Daniel × 10 : 2 = 50

Chilla + suka + Daniel = … ?

Pembahasan :

Diketahui :

5 × Chilla : 10 = 10
suka × 4 : 5 = 20
Daniel × 10 : 2 = 50

Ditanya :

Chilla + suka + Daniel = … ?

Jawab :

A. 5 × Chilla : 10 = 10

$5 × Chilla div 10 = 10$

$5 times a div 10$

$frac{5}{10} a= 10$

$frac{1}{2} a = 10$

$2 times frac{1}{2} a= 10 times 2$

$Chilla = a = 20$

B. suka × 4 : 5 = 20

$suka × 4 div 5 = 20$

$b times 4 div 5 = 20$

$frac{4}{5} b = 20$

$frac{5}{4} times frac{4}{5} b = frac{5}{4} times 20$

$b = 5 times 5$

$suka = b = 25$

C. Daniel × 10 : 2 = 50

$Daniel × 10 div 2 = 50$

$c times 10 div 2 = 50$

$c times 5 = 50$

$5c = 50$

$Daniel = c = 10$

D. Chilla + suka + Daniel

$Chilla + suka + Daniel$

$a + b + c$

$20 + 25 + 10$

$45 + 10$

$= 55 : : : : : : : : : ✓$

Diperoleh bahwa :

– Chilla = 20

– Suka = 25

– Daniel = 10

– Chilla + suka + Daniel = 55

Kesimpulan :

Jadi, nilai dari Chilla + suka + Daniel adalah 55

Soal:

5 x Chilla : 10 = 10

suka x 4 : 5 = 20

Daniel x 10 : 2 = 50

Chilla + suka + Daniel =

Penjelasan dengan langkah-langkah:

5 x Chilla : 10 = 10

5 x 20 : 10 = 10

100 : 10 = 10

suka x 4 : 5 =20

25 x 4 : 5 =20

100 : 5 =20

Daniel x 10 : 2 = 50

10 x 10 : 2 = 50

100 : 2 = 50

Chilla + suka + Daniel =

20 + 25 + 10 =

45 + 10 = 55
