Question

x:3:9/2=15/4:9/2:y find the value of x and y​

Answer 1

Answer:i don't understand this

Step-by-step explanation:

Answer 2

First remove "y" and its corresponding number to find "x" then remove "x" and its corresponding number to get "y".

When we remove "y" we also remove "9/2" corresponding number as it is equivalent so equation becomes

x:3=15/4:9/2

x÷3=15/4÷9/2

x/3=15/4×2/9

x/3=5/6(after solving above right hand side)

x=5/6×3

x=5/2 or 2-1/2 (in proper fraction)

Now again

When we remove "x" we also remove "15/4" corresponding number as it is equivalent so equation becomes

3:9/2=9/2:y (ratio means ÷)

3÷9/2=9/2÷y

3×2/9=9/2×1/y

6/9=9/2y

Cross multiply

6(2y)=9×9

12y=81

÷ both sides by 12

y= 81/12(table of 3 used to cut fractions. We use HCF to find common too)

y=27/4 or 6-3/4(proper fraction).
