Alex scored 10 out of 50 in a test. What percentage does this represent? Answer =

Step 1 ：Let Alex's score be \(a\) and the total possible score be \(t\).

Step 2 ：\(a = 10\) and \(t = 50\)

Step 3 ：To find the percentage, we need to divide Alex's score by the total possible score and then multiply by 100.

Step 4 ：Percentage = \(\frac{a}{t} \times 100\)

Step 5 ：Percentage = \(\frac{10}{50} \times 100\)

Step 6 ：Percentage = \(0.2 \times 100\)

Step 7 ：Percentage = 20

Step 8 ：\(\boxed{20\%}\)
