Name one decimal that is between 0 and 1?
Decimals are a way to represent fractions in a number. Decimals are written using a decimal point, with digits on either side. To compare decimals, look at the digits to the right of the decimal point.
Decimals are numbers that are written in a form that includes a decimal point. For example, 3.14 is a decimal. Decimals can represent fractions and be used to compare quantities that are not whole numbers. Decimals can be rounded to the nearest whole number or another decimal number. For example, 3.14 can be rounded to 3 or 3.1.

Converting Rational Numbers to Decimals Using Long Division
Rational Number - a number that can be expressed as a fraction where the numerator (top number) and denominator (bottom number) are both integers (whole numbers). Long Division - a mathematical method used to divide one number (dividend) by another (divisor) to get the quotient and remainder. Decimal - a number that has a fractional component, expressed as a point followed by a series of digits after it.
Long division can be used to divide polynomials, which are equations with multiple terms, in addition to rational numbers. The long division algorithm was first described in the 12th century by Indian mathematician, Bhaskara. Long division can be used to find the prime factors of a number, which are numbers that can be multiplied together to make the original number.
