Calculate 1/4+3/8
Add, subtract, multiply, or divide fractions and mixed numbers with step-by-step solutions.
1/4 + 3/8
The denominators are different (4 and 8). Find the Least Common Denominator:
LCD(4, 8) = 8
Rewrite each fraction with denominator 8:
= (1×2)/(4×2) + 3/8
= 2/8 + 3/8
Now the denominators match. Add the numerators:
= (2 + 3)/8
= 5/8
= 5/8 (= 0.625 as a decimal)
How to calculate 1/4+3/8
To calculate 1/4+3/8, 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.
