Solve x/42= 3/7 using two different strategies

The solution of x/42= 3/7 using two different strategies is x = 18

Solution:

Given, expression is

We have to solve the above given expression using two different strategies.

Now let us use cross multiplication,

So the value of x is 18.

Now let us use comparison method,

Then, for comparison in our problem denominators should be equal so multiply R.H.S fraction with 6 and divide with 6.

Now by comparison x = 18.  Hence, the value of x is 18.  

c is the answer

step-by-step explanation:

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
