Question

if 10,x,15 and 3 are in proportion find the value of x​

Answer 1

Step-by-step explanation:

Step 1 10×3/15x

Step 2 30/15x

Step 3 x=30/15

Step 4 x=2

Answer 2

$\pink { If \:a : b = c : d , we \:write \: a : b :: c : d }$

$\pink { and \: we \: say \:that \:a,b,c,d \:are }$

$\pink { in \:proportion . }$

$\boxed { \orange { we \:have ,\:a\times d = b\times c}}$

$Here , 10,x ,15 \: and \: 3 \: are \:in \:proportion$

$\implies \frac{10}{x} = \frac{15}{3}$

$\implies x \times 15 = 10 \times 3$

$\implies x = \frac{ 30}{15}$

$\implies x = 2$

Therefore.,

$\red { Value \:of \:x } \green { = 2}$
