Convert Fraction to Decimal: Finding the Decimal Value of 3/20

To solve this problem, we'll utilize multiplication to simplify the conversion process:

• Step 1: Begin with $\frac{3}{20}$.
• Step 2: Identify that multiplying $\frac{3}{20}$ by $\frac{5}{5}$ (which is 1, thus does not change the value) will yield a fraction with a denominator of 100: $\frac{3 \times 5}{20 \times 5} = \frac{15}{100}$.
• Step 3: A denominator of 100 allows straightforward conversion to decimal, with $\frac{15}{100} = 0.15$.

Therefore, the fraction $\frac{3}{20}$ converts to a decimal as 0.15.

This calculation aligns with the answer choice provided, making option : 0.15 the correct one.
