Question

find the value of x in each of the given proportion. (any four)​

Answer 1

Answer:

Step-by-step explanation:

i) 5:3 :: x:6

5/3 = x/6

therefore, 3x = 30

therefore, x = 10.

ii) x:3 :: 4:6

x/3 = 4/6

x = 4/6*3

therefore, x = 2

iii) 9:8 :: 81:x

9/8 = 81/x

9x = 8*81

x = 8*81/9

x = 8*9

x = 72

iv) 24:x :: 18:45

24/x = 18/45

18x = 24*45

x = 1080/18

x = 60
