Answer:

h=5/18

Step-by-step explanation:

Hi there!

If you try to solve 1/2-h=2/9 for h immediately, you will find that you cannot because the denominator is odd for 2/9. Multiply 2 for the numerator and the denominator to get 4/18. Now we have 1/2-h=4/18. Multiply the numerator and denominator by 9 to get 9/18-h=4/18. H=5/18.

Answer:

\boxed{h=\dfrac{5}{18}}

Step-by-step explanation:

\textsf {$\dfrac{1}{2} - h$ = $\dfrac{2}{9}$}

1. Subact  \dfrac{1}{2}  from both sides:

\textsf {$\dfrac{1}{2} - h$ = $\dfrac{2}{9}$}\\\\\textsf {$\dfrac{1}{2}-\dfrac{1}{2} - h$ = $\dfrac{2}{9} -\dfrac{1}{2}$}\\\\\textsf {$-h$ = $\dfrac{4-9}{18}$}\\\\\textsf {$-h$ = $\dfrac{-5}{18}$}

2. Divide both sides by -1

\textsf {$-h$ = $\dfrac{-5}{18}$}\\\div -1  \div-1\\\\ \boxed{h=\dfrac{5}{18}}

Final answer: \boxed{h=\dfrac{5}{18}}

Hope this helps!
