Step-by-Step Solution for Converting 1.88 to a Fraction

Step 1: Understand the Number

The number 1.88 is a decimal, which can be broken into two parts:

  • The whole number part is: 1.
  • The decimal part is: 0.88.

We aim to convert the entire number into a fraction.

Step 2: Isolate the Decimal Part (0.88)

Focus on the decimal part (0.88) and represent it as a fraction.

Step 2.1: Write 0.88 as \( \frac88100 \)

The decimal 0.88 can be read as "88 hundredths." Mathematically, this is:

\[ 0.88 = \frac88100 \]

Step 2.2: Simplify the Fraction

Now simplify \( \frac88100 \) by finding the greatest common divisor (GCD) of 88 and 100.

  • The GCD of 88 and 100 is: 4.
  • Therefore, the simplified fraction is:

\[ \frac2225 \]

Step 3: Combine the Whole Number and Fraction

The original number 1.88 is the sum of the whole number 1 and the fraction \( \frac2225 \).

Combine these as a mixed number:

\[ 1.88 = 1 + \frac2225 = \frac47/25 \]

Step 4: Verify the Answer

To verify, divide \( \frac47/25 \):

\[ \frac47/25 = 1.88 \]

Thus, the fraction is correct.

Final Answer

The decimal 1.88 as a fraction is:

\[ \frac47/25 \]

If expressed as a mixed number:

\[ 1 22/25 \]
