Answer:

a = 18

Step-by-step explanation:

Step 1: Cross-multiply.

  • 0.5 * a = 10*0.9
  • 0.5a =9  

Step 2: Divide both sides by 0.5

  • \frac{0.5a}{0.5} =\frac{9}{0.5}
  • a = \frac{90}{5}
  • a = 18

Step 3: Check if solution is correct.

  • \frac{0.9}{0.5}=\frac{18}{10}
  • \frac{9}{5} =\frac{18}{10}  
  • \frac{18/2}{10/2} =\frac{9}{5}
  • \frac{9}{5} =\frac{9}{5}

Therefore, a = 18.
