Question

If you have the following equation; 4x - 4.5 = 10.73x + 5.7 + 7x, what would you multiply each term by to get rid of the decimals in the equations?

Answer 1

100

Explanation:

You are given the equation

`4x-4.5=10.73+5.7+7x`

There are 5 coefficients:

`4, \ -4.5,\ 10.73,\ 5.7,\ 7`

Two of them are integers

`4,\ 7`

two of them are decimals with one digit after point

`-4.5,\ 5.7`

and one is a decimal with two digits after point

`10.73`

To get rid of fractions, we have to get rid of digits after point. The maximum number of digits after point is 2, then we have to multiply the equation by 100:

`400x-450=1,073x+570+700x`
