the ratio of the number of star to the number of sun to the number of circle is 1:2:3. there are 12 more circle than sun. how many star are there? b. how many s

Bab Perbandingan

Bintang = x
Matahari = 2x
Lingkaran = 3x

Lingkaran
= 2x + 12

a. Lingkaran/Bintang = 3x/x
(2x + 12)/x = 3
2x + 12 = 3x
12 = 3x - 2x
x = 12
There are 12 stars

b. Jumlah perbandingan
= 1 + 2 + 3
= 6

Jumlah seluruh bentuk
= 6 × 12
= 72 bentuk
There are 72 shapes

Bintang = B
Matahari = M
Lingkaran = L

B : M : L = 1 : 2 : 3
L - M = 12
Dalam perbandingan L - M = 1

a. B = 1/1 x 12 = 12
b. Total semua = 6/1 x 12 = 72

Jadikan terbaik ya, thanks
