Question

What should be done to both sides of the equation in order to solve 1/3 x=4? Divide by 4Multiply by 4 Divide by 1/3Multiply by 1/3

Answer 1

The given equation is,

`(1)/(3)x=4`

So, from this equation , we have to find the value of x. The left hand side of the equation has x with 1/3 as coefficient, therefore, inorder to make it x, we have to,

`(1)/(3)x*3\rightarrow x`

as the thress get cancelled. If we do some operation on one side of the equal sign, it is to be applied on the other side also so as to maintain the equivalency.

So here we have to multiply by 3.

But in option, there is no as such given , but it is given that divide by 1/3.

`((1)/(3)x)/((1)/(3))\rightarrow(1)/(3)x*3^{}^{}`

which is equuivalent to multiplying by three.

So the option " Divide by 1/3" is correct.
