Step-by-Step Solution: 1/2 + 2/4
Step 1
Find the Least Common Denominator (LCD)
Notice that 4 is an exact multiple of 2 (2 × 2 = 4). The Least Common Denominator (LCD) is simply 4, meaning we only need to scale one fraction.
LCD(2, 4) = 4
Step 2
Convert to Equivalent Fractions with Common Denominator 4
Multiply the numerator and denominator of 1/2 by 2, and multiply the numerator and denominator of 2/4 by 1 so both fractions share the common base 4.
1 × 2/2 × 2 = 2/4 and 2 × 1/4 × 1 = 2/4
Step 3
Add the Numerators
Now add the numerators (2 + 2 = 4) and keep the common denominator 4 unchanged.
2 + 2/4 = 4/4
Step 4
Simplify to an Exact Whole Number
Notice that the numerator (4) is completely divisible by the denominator (4). Dividing 4 by 4 yields the whole number 1 with zero remainder.
4/4 = 1
Step 5
