Answer:
60 is the least common denominator.
2/3 = 40/60
17/20 = 51/60
Solution
Rewriting input as fractions:
2/3, 17/20
For the denominators (3, 20) the least common multiple (LCM) is 60.
Therefore, the least common denominator (LCD) is 60.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
2/3 = 2/3 × 20/20 = 40/60
17/20 = 17/20 × 3/3 = 51/60
