What is a decimal?

A decimal is a numeral system that includes a point to separate the whole number part from the fractional part. This system makes it easy to work with numbers less than one.

What is a fraction?

A fraction is a mathematical way of showing a part of a whole. It has two parts: the numerator on top and the denominator below, which help express partial values and comparisons.

Step-by-step solution:

Step 1: First, write the decimal as a fraction over 1. This sets up the next steps. 1.42857142857 = $\frac{1.42857142857}{1}$
Step 2: Decimals can have different lengths. We will align the number of digits after the decimal point. For 1.42857142857, we have three digits. This means multiplying the fraction by a factor of 10 for each digit. Factor = 10¹¹ = 100000000000
Step 3: Using this factor, multiply both the numerator and the denominator. $\frac{1.42857142857 × 100000000000}{1 × 100000000000}$ = $\frac{142857142857}{100000000000}$
Step 4: Now we need to simplify the fraction by finding common divisors. The greatest common divisor is 1. Divide both the numerator and the denominator by this common divisor. $\frac{142857142857 ÷ 1}{100000000000 ÷ 1}$ = $\frac{142857142857}{100000000000}$
