Because of the difference between the swings here we need to adjust the ball position to allow for this. As the iron swing is more upright, the club head will travel straighter down the target line, whereas the flatter driver swing will see more of an arc approach to the target line and therefore the ball.
For computers, see Lowest common denominator (computers) . In mathematics, the lowest common denominator or least common denominator (abbreviated LCD) is the least common multiple of the denominators of a set of fractions. It simplifies adding, subtracting, and comparing fractions.
Simplify the fraction. To simply the fraction, you need to find the lowest common denominator, which means that you should divide both the numerator and denominator by any number that divides evenly into both numbers. Since 2 is the numerator, you should see if 2 divides evenly into 12 -- it does because 12 is even.
