simply divide 3/10 to get 0.3 and then divide 3/5 to get 0.6 then just divide 0.3 to 0.6 to get 0.5 or 1/2
Answer:
a : b : c = 12 : 10 : 15
Step-by-step explanation:
Given that: b =
of c
i.e b =
............... 1
2c = 5b
So that;
c =
.................... 2
Also,
4a = 3c
a =
................ 3
⇒ a =
× (
)
a =
................. 4
15b = 8a
b =
................. 5
Comparing the derived equations:
From equations 2 and 3,
a:c =
:
= 4:5
From equations 1 and 2,
b:c =
:
= 2:3
But a common value of b = 15, gives;
a : c = 12 : 15 and b : c = 10 : 15
Thus, a : b : c = 12 : 10 : 15
