Question 1

How do you convert a fraction to a decimal?

Accepted Answer

To convert a fraction to a decimal, divide the numerator (top number) by the denominator (bottom number). For example, 3/4 = 3 ÷ 4 = 0.75. For mixed numbers, convert to an improper fraction first or add the whole number to the decimal result of the fraction part.

Question 2

How do you convert a decimal to a fraction?

Accepted Answer

To convert a decimal to a fraction: 1) Count the decimal places, 2) Write the decimal as the numerator over a power of 10 (10, 100, 1000, etc.) based on decimal places, 3) Simplify the fraction by dividing both numerator and denominator by their GCD. For example, 0.75 = 75/100 = 3/4 when simplified.

Question 3

What is a recurring or repeating decimal?

Accepted Answer

A recurring decimal is a decimal number with digits that repeat infinitely. For example, 1/3 = 0.333... (3 repeats). Our calculator detects common recurring patterns and displays them. Recurring decimals occur when the denominator of a simplified fraction has prime factors other than 2 and 5.

Question 4

How do you simplify a fraction?

Accepted Answer

To simplify a fraction, divide both the numerator and denominator by their Greatest Common Divisor (GCD). For example, 8/12 simplified: GCD of 8 and 12 is 4, so 8÷4 / 12÷4 = 2/3. Our calculator automatically shows both the original and simplified forms.

Question 5

What is an improper fraction?

Accepted Answer

An improper fraction is a fraction where the numerator is greater than or equal to the denominator, like 7/4. It can be converted to a mixed number (1 3/4). Our calculator handles both forms and shows conversions between improper fractions and mixed numbers.

Question 6

Can all fractions be expressed as decimals?

Accepted Answer

Yes, all fractions can be expressed as decimals. They will either be terminating decimals (like 1/4 = 0.25) or repeating decimals (like 1/3 = 0.333...). Terminating decimals occur when the denominator's only prime factors are 2 and/or 5.

Question 7

How accurate is the calculator for repeating decimals?

Accepted Answer

The calculator provides high accuracy for most conversions. For repeating decimals, JavaScript's floating-point precision limits may affect very long patterns. The calculator detects common repeating patterns up to a reasonable length and displays them clearly.

Question 8

What is the difference between proper and improper fractions?

Accepted Answer

A proper fraction has a numerator smaller than the denominator (like 3/4), representing a value less than 1. An improper fraction has a numerator greater than or equal to the denominator (like 7/4), representing a value of 1 or more. Mixed numbers (like 1 3/4) are another way to express improper fractions.
