Step-by-Step Solution for Converting 1.16 to a Fraction

Step 1: Understand the Number

The number 1.16 is a decimal, which can be broken into two parts:

• The whole number part is: 1.
• The decimal part is: 0.16.

We aim to convert the entire number into a fraction.

Step 2: Isolate the Decimal Part (0.16)

Focus on the decimal part (0.16) and represent it as a fraction.

Step 2.1: Write 0.16 as \( \frac16100 \)

The decimal 0.16 can be read as "16 hundredths." Mathematically, this is:

\[ 0.16 = \frac16100 \]

Step 2.2: Simplify the Fraction

Now simplify \( \frac16100 \) by finding the greatest common divisor (GCD) of 16 and 100.

• The GCD of 16 and 100 is: 4.
• Therefore, the simplified fraction is:

\[ \frac425 \]

Step 3: Combine the Whole Number and Fraction

The original number 1.16 is the sum of the whole number 1 and the fraction \( \frac425 \).

Combine these as a mixed number:

\[ 1.16 = 1 + \frac425 = \frac29/25 \]

Step 4: Verify the Answer

To verify, divide \( \frac29/25 \):

\[ \frac29/25 = 1.16 \]

Thus, the fraction is correct.

Final Answer

The decimal 1.16 as a fraction is:

\[ \frac29/25 \]

If expressed as a mixed number:

\[ 1 4/25 \]
