Frequently Asked Questions
How do you add two fractions with different denominators?
To add fractions with different denominators, find the Least Common Denominator (LCD). For example, 1/3 + 1/4: the LCD is 12. Convert: 4/12 + 3/12 = 7/12. In Class 6 and 7 CBSE maths, fraction addition is a core topic. The rule is: make denominators equal, then add the numerators. Always simplify the result to its lowest form.

How do you convert a fraction to a decimal?
To convert a fraction to a decimal, simply divide the numerator by the denominator. For example, 3/4 = 3 ÷ 4 = 0.75, and 1/3 = 0.333... (repeating). Common fractions worth memorising: 1/2 = 0.5, 1/4 = 0.25, 3/4 = 0.75, 1/5 = 0.2. In Indian school exams, converting fractions to decimals is tested in Class 5 through 8 maths chapters.

What is an improper fraction and how is it different from a mixed number?
An improper fraction has a numerator greater than or equal to its denominator — for example, 7/4 or 9/5. A mixed number expresses the same value as a whole number plus a proper fraction: 7/4 = 1¾. In Indian primary school (CBSE Class 5-6), students learn to convert between improper fractions and mixed numbers. Improper fractions are easier to use in arithmetic operations like multiplication and division. Use the free Fraction Calculator on AbacusHand to calculate your exact result instantly.
How do you simplify a fraction to its lowest form?
To simplify a fraction, divide both numerator and denominator by their Highest Common Factor (HCF). For example, 18/24: HCF of 18 and 24 is 6, so 18/24 = 3/4. Simplification makes fractions easier to compare, add, and use in problems. CBSE Class 6 and 7 exams regularly test fraction simplification. If a fraction is already in its simplest form, no further reduction is possible. Use the free Fraction Calculator on AbacusHand to calculate your exact result instantly.
How are fractions used in cooking recipes?
Fractions appear constantly in cooking — recipes often call for 1/2 cup of flour, 3/4 tsp of salt, or 1/3 cup of oil. If you need to double or halve a recipe, you multiply or divide these fractions. For example, doubling 2/3 cup of sugar gives 4/3 = 1 and 1/3 cups. Indian recipes also use fractional quantities for spices like 1/4 tsp of turmeric. Understanding fractions prevents measurement errors in the kitchen. Use the free Fraction Calculator on AbacusHand to calculate your exact result instantly.
