Calculate 1/3+1/4
Add, subtract, multiply, or divide fractions and mixed numbers with step-by-step solutions.
1/3 + 1/4
The denominators are different (3 and 4). Find the Least Common Denominator:
LCD(3, 4) = 12
Rewrite each fraction with denominator 12:
= (1×4)/(3×4) + (1×3)/(4×3)
= 4/12 + 3/12
Now the denominators match. Add the numerators:
= (4 + 3)/12
= 7/12
= 7/12 (= 0.583333 as a decimal)
How to calculate 1/3+1/4
To calculate 1/3+1/4, find the least common denominator (LCD), rewrite each fraction with that denominator, perform the operation on the numerators, and simplify the result to lowest terms.
This is a fraction arithmetic problem — we perform operations on fractions by finding common denominators for addition/subtraction, or multiplying straight across for multiplication/division.
