Question

If x:z = 2:3 and y:z = 1:3 then x:y:z ? (Ratio and proportion)​

Answer 1

Answer:

2:1:3

Step-by-step explanation:

as they have mentioned above

X=2

y=1

z=3

Answer 2

Question:-

If x:z = 2:3 and y:z = 1:3 then x:y:z = ?

Answer:-

x : z = 2 : 3

➵ x/z = 2/3

➵ 3x = 2z ----------( 1 )

y : z = 1 : 3

➵ y/z = 1/3

➵ 3y = z

Multiply both sides by 2

➵ 6y = 2z -------------( 2 )

From ( 1 ) and ( 2 ):-

3x = 6y = 2z

Finding Ratio:-

3x = 6y

➵ x/y = 6/3

➵ x/y = 2/1

➵ x : y = 2 : 1 ---------------( 3 )

6y = 2z

➵ y/z = 2/6

➵ y/z = 1/3

➵ y : z = 1 : 3 ------------------( 4 )

From ( 3 ) and ( 4 ):-

x : y : z = 2 : 1 : 3

Ans. x : y : z = 2 : 1 : 3
