What To Know
- It is written as a quotient of two numbers, where the numerator (top number) indicates the number of parts taken, and the denominator (bottom number) indicates the total number of parts in the whole.
- To convert a mixed number to a fraction, multiply the whole number by the denominator of the fraction and add the numerator.
- To add or subtract fractions with different denominators, find the least common multiple (LCM) of the denominators and convert each fraction to an equivalent fraction with the LCM as the denominator.
Mastering the art of calculating fractions of numbers is a fundamental skill that unlocks a world of mathematical possibilities. Whether you’re a student grappling with algebra, a scientist analyzing data, or a chef following recipes, understanding how to work out fractions is essential. This comprehensive guide will provide you with a step-by-step approach to unraveling the mysteries of fractions, empowering you to solve problems with confidence.
What is a Fraction?
A fraction represents a part of a whole. It is written as a quotient of two numbers, where the numerator (top number) indicates the number of parts taken, and the denominator (bottom number) indicates the total number of parts in the whole. For example, the fraction 1/2 represents one part of a whole that has been divided into two equal parts.
Multiplying a Fraction by a Whole Number
To multiply a fraction by a whole number, simply multiply the numerator by the whole number. The denominator remains the same.
Example:
Multiply 1/3 by 5.
“`
1/3 x 5 = (1 x 5) / 3 = 5/3
“`
Dividing a Whole Number by a Fraction
To divide a whole number by a fraction, flip the fraction and multiply.
Example:
Divide 6 by 1/2.
“`
6 ÷ 1/2 = 6 x 2/1 = 12/1 = 12
“`
Multiplying Fractions
To multiply fractions, multiply the numerators and denominators separately.
Example:
Multiply 1/2 by 3/4.
“`
1/2 x 3/4 = (1 x 3) / (2 x 4) = 3/8
“`
Dividing Fractions
To divide fractions, flip the second fraction and multiply.
Example:
Divide 1/2 by 3/4.
“`
1/2 ÷ 3/4 = 1/2 x 4/3 = 4/6 = 2/3
“`
Converting Mixed Numbers to Fractions
A mixed number is a combination of a whole number and a fraction. To convert a mixed number to a fraction, multiply the whole number by the denominator of the fraction and add the numerator. The result becomes the new numerator, while the denominator remains the same.
Example:
Convert 2 1/2 to a fraction.
“`
2 1/2 = (2 x 2) + 1 / 2 = 5/2
“`
Converting Fractions to Decimals
To convert a fraction to a decimal, divide the numerator by the denominator.
Example:
Convert 3/4 to a decimal.
“`
3/4 = 3 ÷ 4 = 0.75
“`

Popular Questions
Q: How do I find the reciprocal of a fraction?
A: The reciprocal of a fraction is the fraction flipped upside down. For example, the reciprocal of 1/2 is 2/1.
Q: How do I simplify a fraction?
A: Simplify a fraction by finding the greatest common factor (GCF) of the numerator and denominator and dividing both by the GCF. For example, 6/12 can be simplified to 1/2 by dividing both by 6.
Q: How do I add or subtract fractions with different denominators?
A: To add or subtract fractions with different denominators, find the least common multiple (LCM) of the denominators and convert each fraction to an equivalent fraction with the LCM as the denominator. Then, add or subtract the numerators and keep the denominator.
