What is 5/20 plus 3/4? (Answer: 1)

Exact Answer

==================================================
Problem: What is 5/20 plus 3/4?
Formula / Expression: 5/20 + 3/4
Final Answer: 1
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
Notice that 20 is an exact multiple of 4 (4 × 5 = 20). The Least Common Denominator (LCD) is simply 20, meaning we only need to scale one fraction.
Working: LCD(20, 4) = 20

Step 2: Convert to Equivalent Fractions with Common Denominator 20
Multiply the numerator and denominator of 5/20 by 1, and multiply the numerator and denominator of 3/4 by 5 so both fractions share the common base 20.
Working: 5 × 1/20 × 1 = 5/20 and 3 × 5/4 × 5 = 15/20

Step 3: Add the Numerators
Now add the numerators (5 + 15 = 20) and keep the common denominator 20 unchanged.
Working: 5 + 15/20 = 20/20

Step 4: Simplify to an Exact Whole Number
Notice that the numerator (20) is completely divisible by the denominator (20). Dividing 20 by 20 yields the whole number 1 with zero remainder.
Working: 20/20 = 1

Step 5: Decimal & Percentage Representation
Dividing the numerator 1 by denominator 1 yields an exact terminating decimal of 1 (or 100%).
Working: 1 ÷ 1 = 1 (100%)
