Question

How do you solve `4.2\cdot x = 39.04`?

Answer 1

`x~=9.295`

Explanation:

`4.2*x=39.04` means `4.2` times `x` is `39.04`

Hence to find `x` let us divide both sides of `4.2*x=39.04` by `4.2`.

Hence `4.2*x=39.04`

`=>1/4.2xx4.2*x=1/4.2xx39.04`

and `x=39.04/4.2=3904/100xx10/42`

i.e. `x=3904/420=1952/210~=9.295`

Note that only common factor between `3904` and `420` is `2` and hence for further division, we have to use long division or calcuator.
