Answer 1

♥---21*12=2x*7

• 3*12/2=X
• 18=X....

Answer 2

Answer:

If 21:2x= 7:12, then the value of x is 18 and it becomes 21 : 36 = 7: 12

Step-by-step explanation:

Given

21:2x = 7:12

That is,

$\frac{21}{2x}={7}{12}$

$21*12 = 7*2x$

$252 = 14x$

$x =\frac{252}{14}=18$

So,

2x = 18*2 = 36

So, the value of x is 18

21 : 36 = 7: 12
