find the lcd for 4 over 5 and 3 over 9
4/5 and 3/9
To find the lcd, count by 5s and 9s
5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60
9, 18, 27, 36, 45, 54, 63
What is the lcd?
To find the least common denominator (LCD) for the fractions 4/5 and 3/9, we first need to find the least common multiple (LCM) of the denominators.
Step 1: Find the multiples of 5: 5, 10, 15, 20, 25, 30, ...
Step 2: Find the multiples of 9: 9, 18, 27, 36, ...
From the multiples we can see that the least common multiple of 5 and 9 is 45.
Now, to express the fractions with a common denominator of 45, we need to determine the equivalent fractions:
4/5 = (4/5) * (9/9) = 36/45
3/9 = (3/9) * (5/5) = 15/45
Therefore, the LCD for 4/5 and 3/9 is 45.
