a. x = 6/8 = 3/x
perkalian silang sehingga menjadi
= 6x = 8x3
= x = 24 : 6
x = 4 cm
b. x = 8/14 = 5/x
perkalian silang sehingga menjadi
= 8x = 14x5
x = 70:8
= 8,75 cm
- = - ~> Di kali silang
6 3
6X = 3 . 8
6X = 24
X = 24
-
6
# Jadi X = 4
B). 14 X
- = - ~> dikali silang
8 5
8X = 14 . 5
8X = 70
X = 70
-
8
# JADI X = 8,75
