jika B = 40/57
maka C =
-
A. 8/57
B. 1
C. 40/57
D. 56/57
Jawaban:
D. 56/57
Penjelasan dengan langkah-langkah:
B : C = 5 : 7
jika B= 40/57
Berapa C?
5:7=40/57 : C
5/7=(40/57) / C
kali silang maka
40/57 x 7 = 5 x C
280/57 =5C
C= (280/57)/5
C=56/57
Maaf Jika salah
[tex] \dfrac{ \frac{40}{57} }{c} = \dfrac{5}{7} [/tex]
[tex]c = \frac{ \frac{40}{57} \times 7 }{5} [/tex]
[tex]c = \frac{ \cancel{40}}{57} \times 7 \times \frac{1}{ \cancel5} [/tex]
[tex]c = \frac{8}{57} \times 7 [/tex]
[tex]c = \frac{8 \times 7}{57} [/tex]
[tex]c = \frac{56}{57} \: \: \sf(d)[/tex]
