Question

Radical Equations:
What should you multiply the entire equation by when there are fractions?

Answer 1

what the equation?

Answer 2

Give me an example

If all the fractions have the same denominator you would multiply everything by that because

\[\large 5\times (\frac{1}{5} + \frac{2}{5})\]will become
\[\large \cancel{5}\times (\frac{1}{\cancel{5}} + \frac{2}{\cancel{5}})\]
which is just \[\large 1 + 2\]

Answer 3

10/30=20/60

Answer 4

\[\large \frac{10}{30} = \frac{20}{60}\]

Well for that you would just, evaluate it....or cross multiply to see its true, no need to multiply both sides by something

Answer 5

10/30 = 20/60 - due to the numerators and denominators equaling 20/60 when multiplied by 2/2 both sides of the proportion are similar
