Step-by-Step Solution: 1/2 + 4/8
Step 1
Find the Least Common Denominator (LCD)
Notice that 8 is an exact multiple of 2 (2 × 4 = 8). The Least Common Denominator (LCD) is simply 8, meaning we only need to scale one fraction.
LCD(2, 8) = 8
Step 2
Convert to Equivalent Fractions with Common Denominator 8
Multiply the numerator and denominator of 1/2 by 4, and multiply the numerator and denominator of 4/8 by 1 so both fractions share the common base 8.
1 × 4/2 × 4 = 4/8 and 4 × 1/8 × 1 = 4/8
Step 3
Add the Numerators
Now add the numerators (4 + 4 = 8) and keep the common denominator 8 unchanged.
4 + 4/8 = 8/8
Step 4
Simplify to an Exact Whole Number
Notice that the numerator (8) is completely divisible by the denominator (8). Dividing 8 by 8 yields the whole number 1 with zero remainder.
8/8 = 1
