Question

15
-------- = 20/16
y+4


y-3
---- = 21/14
6

x/9=12/8

hitunglah nilai x dan y pada perbandingan perbandingan brkt ini

Answer 1

X/9=12/8
x= 3/2 . 9
x= 13,5

15/y+4 = 20/16
(y+4).20 = 15.16
20y+80 = 240
20y = 240-80
y= 160/20 = 8

y-3/6 = 21/14
(y-3).14 = 6.21
14y - 42 = 126
14y = 126+42
y= 168/14 = 12

semoga bermanfaat
