Step-by-Step Solution: 4/14 + 3/4
Step 1
Find the Least Common Denominator (LCD)
The denominators 14 and 4 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 28 (which is smaller than their product 14 × 4 = 56, keeping the calculation simpler).
LCD(14, 4) = 28
Step 2
Convert to Equivalent Fractions with Common Denominator 28
Multiply the numerator and denominator of 4/14 by 2, and multiply the numerator and denominator of 3/4 by 7 so both fractions share the common base 28.
4 × 2/14 × 2 = 8/28 and 3 × 7/4 × 7 = 21/28
Step 3
Add the Numerators
Now add the numerators (8 + 21 = 29) and keep the common denominator 28 unchanged.
8 + 21/28 = 29/28
Step 4
Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 29 and 28 is 1, confirming that 29/28 cannot be reduced further—it is already in its simplest irreducible form.
29/28
Step 5
Convert Improper Fraction to a Mixed Number
Since the numerator (29) is greater than the denominator (28), divide 29 by 28: it goes in 1 whole time(s) with a remainder of 1, giving the mixed number 1 1/28.
29/28 = 11/28
Step 6
Decimal & Percentage Representation
Dividing the numerator 29 by denominator 28 produces a repeating decimal (approximately 1.035714, or 103.5714%).
