Responses

21=5x
Start Fraction 2 over 1 End Fraction equals Start Fraction 5 over x End Fraction

1:3::5:x
ratio of 1 to 3 colon colon ratio of 5 to x

12=5x
Start Fraction 1 over 2 End Fraction equals Start Fraction 5 over x End Fraction

1:2=5:x

Answer 1

To express the statement "1 is to 2 as 5 is to x" in fractional notation, you want to set up a proportion. The correct representation is:

\[ \frac{1}{2} = \frac{5}{x} \]

So, the answer is:

Start Fraction 1 over 2 End Fraction equals Start Fraction 5 over x End Fraction (or simply \(\frac{1}{2} = \frac{5}{x}\)).

You can also see this expressed as \(1:2 = 5:x\), but the fractional notation is the direct conversion to proportions.
