Step-by-Step Solution for Converting 1.58 to a Fraction

Step 1: Understand the Number

The number 1.58 is a decimal, which can be broken into two parts:

  • The whole number part is: 1.
  • The decimal part is: 0.58.

We aim to convert the entire number into a fraction.

Step 2: Isolate the Decimal Part (0.58)

Focus on the decimal part (0.58) and represent it as a fraction.

Step 2.1: Write 0.58 as \( \frac58100 \)

The decimal 0.58 can be read as "58 hundredths." Mathematically, this is:

\[ 0.58 = \frac58100 \]

Step 2.2: Simplify the Fraction

Now simplify \( \frac58100 \) by finding the greatest common divisor (GCD) of 58 and 100.

  • The GCD of 58 and 100 is: 2.
  • Therefore, the simplified fraction is:

\[ \frac2950 \]

Step 3: Combine the Whole Number and Fraction

The original number 1.58 is the sum of the whole number 1 and the fraction \( \frac2950 \).

Combine these as a mixed number:

\[ 1.58 = 1 + \frac2950 = \frac79/50 \]

Step 4: Verify the Answer

To verify, divide \( \frac79/50 \):

\[ \frac79/50 = 1.58 \]

Thus, the fraction is correct.

Final Answer

The decimal 1.58 as a fraction is:

\[ \frac79/50 \]

If expressed as a mixed number:

\[ 1 29/50 \]
