Question

125/120=75/x what is x

Answer 1

Given: $125/120=75/x$

We have to find the value of$x$.

• By using the concept of equation shifting, we are solving the above equation.  
• For this, we will separate the variables on one side and the constant on another side.  
• Then, we will simplify the equation.

We are solving in the following way:

We have,

$125/120=75/x$

$=>\frac{125}{120} =\frac{75}{x} \\\\=>125\times x=75\times 120\\\\=>125x=9000\\\\=>x=\frac{9000}{125} \\\\=>x=72$

Hence, the value of$x$ will be$72$.

Answer 2

As per given information,

$\frac{125}{120} = \frac{75}{x}$

We have to find out the the value of x.

By using the equation shifting property we can find out the value of x.

Given ,

$\frac{125}{120} = \frac{75}{x}$

By shifting Denominator of both fraction to the opposite side it becomes multiplication.

So expression becomes,

$125 \times x = 75 \times 120$

Shift 125 other side it becomes divide

$x = \frac{75 \times 120}{125}$

By dividing 75 and 125 by 25 we get

$x = \frac{3 \times 120}{5}$

Divide 120 by 5 we get

$x = 3 \times 24$

$x = 72$

So,

The value of x is 72.

Verify ans -

$\frac{75}{72} = \frac{25}{24}$

$\frac{125}{120} = \frac{25}{24}$

As after solving both the fraction gives same fraction means answer is right.
