What it is 2 over 5 9ths times 1 over 1 half?

To solve ( \frac{2}{5} \times \frac{9}{1} \times \frac{1}{\frac{1}{2}} ), first, simplify ( \frac{1}{\frac{1}{2}} ) to 2. Now, the expression becomes ( \frac{2}{5} \times 9 \times 2 ). This simplifies to ( \frac{2 \times 9 \times 2}{5} = \frac{36}{5} ) or ( 7.2 ) when expressed as a decimal.
