Step-by-Step Solution for Converting 1.59 to a Fraction

Step 1: Understand the Number

The number 1.59 is a decimal, which can be broken into two parts:

• The whole number part is: 1.
• The decimal part is: 0.59.

We aim to convert the entire number into a fraction.

Step 2: Isolate the Decimal Part (0.59)

Focus on the decimal part (0.59) and represent it as a fraction.

Step 2.1: Write 0.59 as \( \frac59100 \)

The decimal 0.59 can be read as "59 hundredths." Mathematically, this is:

\[ 0.59 = \frac59100 \]

Step 2.2: Simplify the Fraction

Now simplify \( \frac59100 \) by finding the greatest common divisor (GCD) of 59 and 100.

• The GCD of 59 and 100 is: 1.
• Therefore, the simplified fraction is:

\[ \frac59100 \]

Step 3: Combine the Whole Number and Fraction

The original number 1.59 is the sum of the whole number 1 and the fraction \( \frac59100 \).

Combine these as a mixed number:

\[ 1.59 = 1 + \frac59100 = \frac159/100 \]

Step 4: Verify the Answer

To verify, divide \( \frac159/100 \):

\[ \frac159/100 = 1.59 \]

Thus, the fraction is correct.

Final Answer

The decimal 1.59 as a fraction is:

\[ \frac159/100 \]

If expressed as a mixed number:

\[ 1 59/100 \]
