Question

Find x if 4, x, 32, 64 are in proportion​

Answer 1

Answer:

$x=16$.

Step-by-step explanation:

If they are in proportion then:

$4*1=4$

$4*y=x$

$4*8=32$

$4*16=64$

So, we see a pattern. In that ways proportion will be: $y=4$ & $x=16$.

So, answer is $x=16$.

Answer 2

Answer:

We can write,

$\frac{4}{x} = \frac{32}{64}$

Cross Multiplication :-

$➺32 \times x = 64 \times 4$

$➺x = \frac{64 \times \cancel{4}}{ \cancel{32} \: ^{ 8} }$

$➺x = \frac{ \cancel{64} \: { }^{8} }{ \cancel{8}}$

$➺x = 8$

Therefore, The value of x is 8.
