Question

$\frac{3}{8} = \frac{18}{x}$
tell me please answer plz bro ​

Answer 1

Answer -

• The value of x = 48.

To find -

• The value of x.

Step-by-step explanation -

$\implies \sf\dfrac{3}{8} = \dfrac{18}{x}$

$\sf\implies 8 \times 18= x \times 3$

$\sf \implies 144 = 3x$

$\sf\implies \cancel{\dfrac{144}{3}} = x$

$\implies \sf 48 = x$

• To check our answer, let's substitute the value of "x" in the equation and see whether LHS = RHS.

LHS :

$\leadsto\tt \dfrac{3}{8}$

RHS :

$\leadsto \tt \dfrac{18}{x}$

$\leadsto \tt \cancel{\dfrac{18}{48} }$

$\leadsto \tt \dfrac{3}{8}$

LHS = RHS

Hence verified!!

Answer 2

Question :-

Find the value of x : $\rm{ \frac{3}{8} = \frac{18}{x} }$

Solution :-

Here, we have two fractions and we need to the value of x is in the 2nd fraction in that case we use the cross multiplication and find the value of x.

Step by step explanation :-

$\sf:\longmapsto{ \frac{3}{8} = \frac{18}{x} } \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \sf:\longmapsto{8 \times 18 = 3 \times x} \\ \\ \sf:\longmapsto{3x = 144} \: \: \: \: \: \: \: \: \: \\ \\ \sf:\longmapsto{}x = \frac{144}{3} \: \: \: \: \: \: \: \: \: \: \\ \\ \sf:\longmapsto{} \boxed{ \sf{x = 48}} \: \: \: \: \: \: \: \: \:$

• x = 48

V E R I F I C A T I O N :

$\sf:\longmapsto{ \frac{3}{8} = \frac{18}{ \red{48}} } \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \sf:\longmapsto{3 \times 48 = 18 \times 8} \: \\ \\:\longmapsto \boxed{\bf\red{144 = 144}} \: \: \: \: \: \: \:$
