y=12

hope it helps u dear☺️☺️☺️

Answer 2

Step-by-step explanation:

Given:-

4 : 3 = y : 9

To find:-

Find the value of y ?

Solution:-

Method-1:-

Given that

4 : 3 = y : 9

It can be written as

4/3 = y/9

On applying cross multiplication then

=> 3×y = 4×9

=> 3 × y = 36

=> y = 36/3

=> y = 12

The value of y = 12

Method-2:-

Given that

4 : 3 = y : 9

Product means = 3×y = 3y

Product of extremes =4×9 = 36

I'm Proportion,

The Product of extremes = The Product of means

=> 3y = 36

=> y = 36/3

=> y = 12

the value of y = 12

Answer:-

The value of y for the given problem is 12

Used formulae:-

• a:b can be written as a/b

• The equality of ratios is called Proportion.

• In Proportion,The Product of extremes = The Product of means
